Yugioh card ruling I-K

ICARUS ATTACK
“Icarus Attack” targets 2 cards. Even if 1 of the target cards is a Spell or Trap and it is activated in a chain, both cards will still be destroyed.

You cannot choose “Icarus Attack” itself for 1 of its 2 targets.


IMPERIAL IRON WALL
Effects that requiring removing a card from play as a cost ("Cyber Valley's" first effect, etc.), cannot be activated while "Imperial Iron Wall" is active.

While "Imperial Iron Wall" is active, optional effects that would remove card(s) from play cannot be activated, so the effect of "D.D. Crow", "Dark Core", "Bottomless Trap Hole", "Nobleman of Crossout", cannot be activated.

While "Imperial Iron Wall" is active, cards that are removed from play when destroyed or otherwise removed from the field ("Dark Magician of Chaos", etc.), will not be removed from play. If it was destroyed, it is sent to the Graveyard. If it was being returned to its owner's hand or Deck, it will be returned to the owner's hand or Deck instead of being removed from play.

If "Macro Cosmos" or "Dimensional Fissure" is active while "Imperial Iron Wall" is active, cards that would be removed from play when sent to the Graveyard are sent to the Graveyard instead.

"Return from the Different Dimension" and "Emergency Teleport" can still be activated while "Imperial Iron Wall" is active. If "Imperial Iron Wall" is active in the End Phase, the Special Summoned monster(s) is not removed from play.

If "Caius the Shadow Monarch" is Tribute Summoned while "Imperial Iron Wall" is active, "Caius the Shadow Monarch's" effect still activates because it is mandatory, but its effect disappears when it resolves.

If "Necroface" is removed from play, activating its effect, and "Imperial Iron Wall" is chained, "Necroface's" effect disappears when it resolves.

"Allure of Darkness" (or "Common Charity", etc.) cannot be activate while "Imperial Iron Wall" is active. If you activate "Allure of Darkness" and "Imperial Iron Wall" is chained, after drawing 2 cards you will reveal 1 DARK Monster from your hand, and the revealed DARK Monster remains in your hand. If you do not have any DARK Monsters in your hand, your entire hand is sent to the Graveyard.

Cards like "Bottomless Trap Hole" and "Nobleman of Crossout" cannot be activated while "Imperial Iron Wall" is active. If you activate "Bottomless Trap Hole" and "Imperial Iron Wall" is chained, the destroyed monster is sent to the Graveyard instead of being removed from play. If you activate "Nobleman of Crossout" and "Imperial Iron Wall" is chained, the face-down monster is destroyed and is sent to the Graveyard instead of being removed from play, but the effect that removes Flip Effect monsters in the Deck from play is not applied.

"Book of Life" cannot be activated while "Imperial Iron Wall" is active. If "Book of Life" is activated and "Imperial Iron Wall" is chained, the Zombie-Type monster is Special Summoned, but the opponent's monster is not removed from play.

If "Imperial Iron Wall" is active, "D.D. Warrior Lady's" effect cannot be activated. The effects of "D.D. Warrior" and "D.D. Assailant" will still activate, but their effects will disappear when they resolve.

If "Quillbolt Hedgehog" is Special Summoned with its effect, when it is removed from the field while "Imperial Iron Wall" is active it is not removed from play. While "Imperial Iron Wall" is active, if it is Tributed or used as a Synchro Material Monster for a Synchro Summon, it will be sent to the Graveyard.

IMPERIAL ORDER
When "Imperial Order" is activated, "Mystical Space Typhoon" can be chained to destroy it.

If you chain "Imperial Order" when a Spell Card is activated, "Imperial Order" will resolve first and negate the Spell Card.

If you activate "Imperial Order" while Equip Spell Cards are equipped to monsters, the Equip Spell Cards remain equipped to the monsters but their effects are negated.

"Imperial Order" cannot be activated in the Damage Step, so you cannot activate it to negate "Rush Recklessly", etc. in the Damage Step.

Spell Cards can still be activated while "Imperial Order" is active, but their effects are negated.

IMPRISONED QUEEN ARCHFIEND
Paying 1000 Life Points during your Standby Phase is a maintenance cost.

If your Life Points are 1000 or less during your Standby Phase, you cannot pay for "Imprisoned Queen Archfiend" so it is destroyed.

INABA WHITE RABBIT
This card can only attack Life Points directly. It cannot attack another monster. If the opponent controls "Patrician of Darkness" and you attack with "Inaba White Rabbit", it is still a direct attack; they cannot select a monster as the attack target.

However, if the opponent controls a monster equipped with "Ring of Magnetism", your "Inaba White Rabbit" must attack the equipped monster if you chose to attack.

INFERNAL DRAGON
If "Infernal Dragon" attacks, and is then flipped face-down, it will not be destroyed during the End Phase. Even if it is flipped face-up again during the same turn, it will not be destroyed.

If "Infernal Dragon" attacks, and control of it is switched to the opponent that turn, it will still be destroyed during the End Phase.

Even if "Infernal Dragon's" attack is negated by "Magic Cylinder", etc., it will still be destroyed during the End Phase.

The second effect of "Infernal Dragon" activates in the Graveyard. If it is destroyed while your opponent controls it, the original owner can choose to activate this effect.

The second effect of "Infernal Dragon" can be activated even if it was treated as an Equip Card when destroyed.

INFERNAL INCINERATOR
Discarding your hand is a cost to Normal Summon or Set this card. It will not activate the effect of a card like “Goldd, Wu-Lord of Dark World”.

You must have at least 1 other card in your hand, besides “Infernal Incinerator”, to discard when your Normal Summon or Set “Infernal Incinerator”.

This card can be Special Summoned (even from your Deck, with a card like “Monster Gate”). You do not have to discard your hand when you Special Summon this card.

When you Normal Summon or Set “Infernal Incinerator”, it does not start a chain even though you are using the monster’s effect to do so.

INFERNO
When "Inferno" battles with another monster with equal ATK, "Inferno"'s effect is not activated because it must destroy the other monster "and send it to the Graveyard", and at that time, Inferno is no longer on the field to activate its effect.

If "Inferno" attacks a face-down "Cyber Jar", "Inferno" is destroyed by the effect of "Cyber Jar" and "Inferno"'s effect is not activated.

INFERNO FIRE BLAST
No copies of "Red-Eyes B. Dragon" can attack if you activate "Inferno Fire Blast".

If "Red-Eyes B. Dragon" attacked, you cannot activate "Inferno Fire Blast" during Main Phase 2, but if "Red-Eyes B. Dragon" did not attack, you can activate "Inferno Fire Blast" during Main Phase 2.

As long as a "Red-Eyes B. Dragon" is on the field when you activate "Inferno Fire Blast", "Inferno Fire Blast" still resolves normally even if "Red-Eyes B. Dragon" is no longer on the field when "Inferno Fire Blast" resolves.

If you control "Red-Eyes B. Dragon" and activate "Inferno Fire Blast" to inflict damage, and then after that resolves you activate "Non-Spellcasting Area", "Red-Eyes B. Dragon" still cannot attack because "Non-Spellcasting Area" will not negate the condition.

If "Imperial Order" is chained to "Inferno Fire Blast", the effect of "Inferno Fire Blast" is negated but "Red-Eyes B. Dragon" cannot attack. However, if "Magic Jammer" negates the activation of "Inferno Fire Blast", your "Red-Eyes B. Dragon" can attack.

If you activate "Inferno Fire Blast" while "Non-Spellcasting Area" is active, the effect of "Inferno Fire Blast" disappears.

If you only have 1 "Red-Eyes B. Dragon" on the field, you can activate multiple copies of "Inferno Fire Blast" designating that same "Red-Eyes B. Dragon".

INFERNO RECKLESS SUMMON
"Inferno Reckless Summon" does not target. Your opponent chooses a monster on his/her side of the field when "Inferno Reckless Summon" resolves.

"Inferno Reckless Summon" cannot be activated in the Damage Step.

If there are not enough available Monster Zone spaces for each monster that will be Special Summoned, the monsters that cannot be Special Summoned are sent to the Graveyard instead.

"Inferno Reckless Summon" cannot be activated when your monster is Special Summoned face-down. Your opponent cannot select a face-down monster when resolving "Inferno Reckless Summon".

Your opponent cannot chose a monster that cannot be Special Summoned.

When resolving "Inferno Reckless Summon", first the player that activated "Inferno Reckless Summon" Special Summons his/her monsters, and then the opponent Special Summons his/her monsters. The monsters are treated as being Special Summoned at the same time.
"Inferno Reckless Summon" cannot be activated when multiple monsters are Special Summoned by the same effect.

"Inferno Reckless Summon" cannot be activated when you Special Summon a monster token. Your opponent cannot choose a monster token.

If the monster you Special Summon will have 1500 or less ATK when it is Special Summoned because of a card effect, you can activate "Inferno Reckless Summon".

If an effect is chained that removes your Special Summoned monster from the field or flips it face-down, your opponent will still Special Summon his/her monsters. If an effect is chained that removes your opponent's only face-up monster from play or flips it face-down, your monsters are still Special Summoned. If your Special Summoned monster and your opponent's only face-up monster are flipped face-down or removed from the field, the effect of "Inferno Reckless Summon" disappears.

When you Special Summon a Fusion Monster or Ritual Monster with 1500 or less ATK and you have additional copies in your Graveyard that can be Special Summoned from the Graveyard, you can activate "Inferno Reckless Summon".

If you Special Summon a monster that cannot be Special Summoned from the Graveyard, you can activate "Inferno Reckless Summon" but copies in the Graveyard are not Special Summoned.

You can activate "Inferno Reckless Summon" when the only face-up monster your opponent controls is a monster token or a monster that is Limited. In this case you will Special Summon, but your opponent will not.

If an effect is chained that increases the ATK of your Special Summoned monster above 1500 ATK, your monsters are still Special Summoned.

If you activate "Inferno Reckless Summon" when you Special Summon "Proto-Cyber Dragon", you will Special Summon "Cyber Dragon" from your hand, Deck, and Graveyard.

You can activate "Inferno Reckless Summon" when your opponent Special Summons a monster with 1500 or less ATK onto your side of the field.

If either player does not Special Summon monsters so that they have 3 monsters with the same name in play after resolving "Inferno Reckless Summon," the opponent can check that player's hand and Deck to verify that they have Summoned all possible copies of the chosen monster. If that monster is Limited or Semi-Limited, and the maximum number of copies allowed per Deck are on that player's side of the field the field, in their Graveyard or in their Removed Zone, their opponent can not check their hand and Deck for additional copies.

INFERNO TEMPEST
If you attack "Blue-Eyes White Dragon" with "Ojama Green" or some other 0 ATK monster, you can activate "Inferno Tempest" after damage calculation. Then "Ojama Green" is sent to the Graveyard after "Inferno Tempest" resolves.

INFINITE DISMISSAL
Level 3 or lower Monster Cards Normal Summoned or Flip Summoned before "Infinite Dismissal" is activated are destroyed if they were Normal Summoned or Flip Summoned during the same turn "Infinite Dismissal" is activated.

INJECTION FAIRY LILY
You can activate this card’s effect during both players’ Damage Steps, at damage calculation. You can activate it only once per Damage Step, but if "Injection Fairy Lily" is involved in multiple battles in the same turn, you can activate it once during each battle.

You cannot increase this card’s ATK by 6000 points by paying 4000 Life Points.

The ATK increase only lasts for that 1 Damage Step. If this card is involved in multiple battles during the same turn, you must pay 2000 Life Points each battle if you wish to keep increasing its ATK.

Activating this card’s effect does not cause a replay.

You may activate this card’s effect even when it is attacking directly.

If your "Injection Fairy Lily" is in battle with the opponent’s "Injection Fairy Lily" the turn player must decide to use its effect or not first. The opponent can then activate their "Injection Fairy Lily" effect. If both effects are activated, it forms a chain.

If this card is equipped with "Heart of Clear Water" and you activate its effect to increase its ATK, the "Heart of Clear Water" is immediately destroyed.

The effect of "Mirror Wall" will reduce "Injection Fairy Lily"’s ATK by half before you decide to use its effect or not. So if you activate its effect, its ATK will be 3200. If 2 copies of "Mirror Wall" are active, its ATK will be 3100.

INSECT PRINCESS
While "Insect Princess" is on your side of the field, if you attack your opponent's face-down Insect-Type monster, it is changed to Attack Position after being flipped face-up (before damage calculation).

While "Insect Princess" is on your side of the field, your opponent can change the Battle Position of his Insect-Type monsters once during his turn, but the Battle Position is immediately changed back to Attack Position.

When you have "Insect Princess" and a Defense Position "Crass Clown" on your side of the field, and "DNA Surgery" is making "Crass Clown" an Insect-Type, and your opponent takes control of "Crass Clown" with "Change of Heart", "Crass Clown" is changed to Attack Position because of "Insect Princess"' effect and its effect activates.

"Insect Princess" gains 500 ATK if she destroys an Insect-Type Monster Token.

INSECT QUEEN
Insect Monster Tokens are placed during the End Phase for each monster "Insect Queen" destroyed that turn (1 for 1).

Insect Monster Tokens are placed during the End Phase, not during the Battle Phase when "Insect Queen" destroys a monster.

The Insect Monster Token is Special Summoned to the side of the field of the player who controls "Insect Queen" at the time the Insect Monster Token is Summoned, even if control of "Insect Queen" changed between the Battle Phase and the End Phase.

If "Insect Queen" destroys a monster but is not on the field during the End Phase, no Insect Monster Token is Special Summoned.

No Insect Monster Token is Special Summoned if it is impossible (due to "Jam Breeding Machine", etc.).

If you want to use "Royal Oppression" to negate the Special Summon of an Insect Monster Token, you chain it to the activation of "Insect Queen"’s effect during the End Phase.

If you Tribute "Pinch Hopper" to attack with Insect Queen, you can activate "Pinch Hopper"’s effect.

INSPECTION
"Inspection's" effect can be activated multiple times during the same Standby Phase.

INSTANT FUSION
Because the Summon from “Instant Fusion” is a Fusion Summon, Fusion Monsters with the text "A Fusion Summon of this monster can only be conducted with the above Fusion Material Monsters.” cannot be Special Summoned with “Instant Fusion”.

Since the Special Summon from “Instant Fusion” is treated as a Fusion Summon, you can use “Premature Burial” etc. on the Fusion Monster if it is destroyed.

Even if “Non-Spellcasting Area” is active, a Fusion Monster that is not an Effect Monster (such as “Flame Swordsman”) will still be affected by the restrictions on “Instant Fusion”. So it still cannot attack and it is still destroyed at the end of this turn.

Even though only 1 copy of this card can be activated each turn, you can chain “Serial Spell” to it to duplicate the effect.

If “Destiny Hero – Diamond Dude” uses its effect and reveals “Instant Fusion”, you can still activate another “Instant Fusion” that same turn.

INSTANT NEO SPACE
When "Instant Neo Space" and the equipped monster are destroyed by the same effect, "Instant Neo Space's" effect does not activate.

INTERCEPT
"Intercept" targets the Tribute Summoned monster.

If the Tribute Summoned monster has an effect that activates when it is Tribute Summoned, the player that Tribute Summoned the monster activates its effect. "Intercept" is chained to the monster's effect.

"Intercept" cannot be activated when "Jinzo" is Tribute Summoned, because "Jinzo's" effect is already applied and prevents Trap Cards from being activated.

INTERDIMENSIONAL MATTER TRANSPORTER
A monster removed with "Interdimensional Matter Transporter" doesn't occupy a Monster Card Zone. If there are no Monster Card Zones available when it returns, it is destroyed.

If you control your opponent's monster because of "Change of Heart" or "Snatch Steal", and remove the monster with "Interdimensional Matter Transporter", the monster returns to your side of the field, then immediately returns to your opponent's side of the field.

A monster returned to the field because of "Interdimensional Matter Transporter" returns in the same Battle Position that it was in when it was removed from the field.

If a Spirit Monster is returned to the field with "Interdimensional Matter Transporter" the same turn it was Summoned or flipped face-up, it returns to the field and then returns to the owner's hand.

When a Fusion Monster is returned to the field with "Interdimensional Matter Transporter" the same turn it was Special Summoned with "Summoner of Illusions" or "Magical Scientist", the Fusion Monster is not destroyed or returned to the Extra Deck.

When an Archfiend is returned to the field with "Interdimensional Matter Transporter" after it was Special Summoned with "Archfiend's Roar", it is not destroyed by "Archfiend's Roar"'s effect.

When "Karate Man", or a monster affected by "Limiter Removal", is removed from play with "Interdimensional Matter Transporter", it is not destroyed that turn because the effect of "Karate Man"/"Limiter Removal" is reset.

INTERDIMENSIONAL WARP
“Interdimensional Warp” targets the monster you control and your opponent’s monster with A-Counter(s).

INTERPLANETARY INVADER 'A'
This effect does not target.

"Interplanetary Invader 'A's" effect first activates at the end of the damage step when it is attacked, but it does not yet take control of the attacking monster. At the end of the Battle Phase its effect starts another Chain, this time taking control of every monster that attacked it during the Battle Phase.

Your opponent's monsters that you take control of with "Interplanetary Invader 'A''s" effect remain under your control when "Interplanetary Invader 'A'" is removed from the field or flipped face-down.

"Interplanetary Invader 'A's'" effect activates even if "Interplanetary Invader 'A'" is destroyed in battle or removed from play. If "Interplanetary Invader 'A'" is returned to the Deck by "Grave Protector", etc., its effect will not activate.

If the monster that attacks your "Interplanetary Invader 'A'" is flipped face-down before the end of the Battle Phase, you will still take control of it during the end of the Battle Phase.

If "Interplanetary Invader 'A'" is attacked by multiple monsters during the Battle Phase, at the end of the Battle Phase you will take control of every monster that attacked it.

If a Level 4 or higher monster attacks "Interplanetary Invader 'A'" and "Gravity Bind" is activated, "Interplanetary Invader 'A's'" effect does not activate because the attack did not proceed to the Damage Step.

If "Interplanetary Invader 'A'" is destroyed without applying damage calculation ("Sasuke Samurai #4", etc.), its effect does not activate.

If you do not have any open Monster Card Zones when “Interplanetary Invader ‘A’’s” effect activates, any monster that you would have gained control of will be destroyed.

INTRODUCTION TO GALLANTRY
If your opponent has 4 or fewer cards in their hand when this card’s effect resolves, they will still discard 1 card at random.

INVADER OF DARKNESS
"Invader of Darkness" prevents the activation of Quick-Play Spell Cards, but doesn't negate their effects. So if your opponent activates a Quick-Play Spell Card and you chain "Call of the Haunted" to Special Summon "Invader of Darkness", he does not negate the activation or effect of the Quick-Play Spell Card.

INVASION OF FLAMES
The effect of this monster prevents the activation of Trap Cards that can be activated when a monster is Normal Summoned, such as "Trap Hole" and "Torrential Tribute".

You can activate Trap Cards later in the turn.

You can negate the Normal Summon of this monsters with "Horn of Heaven" or "Solemn Judgment". (In which case the Normal Summon failed and the effect of the monster is not applied.)

The effect of this monster is applied to both players (so you cannot activate "Pineapple Blast" in response to your Normal Summon of this monster).

This is a Continuous Effect that you cannot chain to.

IRIS, THE EARTH MOTHER
The effect of “Iris, the Earth Mother” is a Trigger Effect. So it will start a new chain itself.

“Iris, the Earth Mother” must have been on the field before the chain began and must have been on the field throughout the entire chain in order for its effect to activate.

The effect of “Iris, the Earth Mother” will still activate even if some steps of the chain have their activation negated. (Or even if “Vanity’s Call” negates all Links in the chain.)

IRON CHAIN BLASTER
Sending 1 "Iron Chain" monster you control to the Graveyard is a cost. You can only send a face-up "Iron Chain" monster.

"Iron Chain Blaster" can send itself to the Graveyard to activate its effect.

IRON CHAIN COIL
"Iron Chain Coil's" effect targets 1 face-up "Iron Chain" monster you control.

IRON CHAIN DRAGON
Removing from play all "Iron Chain" monsters in your Graveyard is not a cost.

IRON CHAIN REPAIRMAN
"Iron Chain Repairman's" second effect targets 1 Level 4 or lower "Iron Chain" monster in your Graveyard.

If "Iron Chain Repairman" attacks and its attack is negated, it cannot activate its second effect in Main Phase 2.

IRON CHAIN SNAKE
"Iron Chain Snake's" first effect targets 1 face-up monster your opponent controls.

The player that controlled the equipped monster when it was destroyed sends cards from the top of their Deck to the Graveyard.

If "Iron Chain Snake" is equipped to a monster with another card's effect, the equipped monster does not lose ATK and DEF. However, when the equipped monster is destroyed by battle and sent to the Graveyard, the effect of "Iron Chain Snake" activates.

When the equipped monster is destroyed by battle and sent to the Graveyard, if its controller has fewer cards in their Deck than the Level of the destroyed monster, every card left in their Deck is sent to the Graveyard.

IZANAGI
"Izanagi's" effect is not applied if it is face-down during the End Phase.

JADE INSECT WHISTLE
The monster selected for "Jade Insect Whistle" is chosen when the effect resolves, not when it is activated, so "Jade Insect Whistle" doesn't target.

If your opponent claims to have no Insect-Type monsters in his/her Deck when your "Jade Insect Whistle" resolves, you can check the Deck to make sure.

A face-up "Parasite Paracide" can be selected with "Jade Insect Whistle".

JADE KNIGHT
If "Jade Knight" is attacked while face-down, its effect does not activate when it is destroyed by battle.

JAIN, LIGHTSWORN PALADIN
If you do not have enough cards to send to the Graveyard remaining in your Deck when resolving the effect of a “Lightsworn” monster or “Judgment Dragon,” all cards remaining in your Deck are sent to the Graveyard. For example, if you control “Jain, Lightsworn Paladin” and its effect activates during your End Phase when you have only 1 card remaining in your Deck, that card will be sent to the Graveyard.

If the effect of a “Lightsworn” monster to send cards from the top of your Deck to your Graveyard during the End Phase is negated by the effect of "Light and Darkness Dragon," that “Lightsworn” monster’s effect activates again in the same End Phase.

If an effect chained to a “Lightsworn” monster’s (or “Judgment Dragon’s”) effect to send cards from your Deck to the Graveyard during the End Phase that removes that “Lightsworn” monster from the field, the “Lightsworn” monster’s effect does not resolve.

JAM BREEDING MACHINE
You may Set monsters when you have this card active on your side of the field, but you cannot Flip Summon them.

You may Summon a monster and then activate this card.

You cannot activate "Scapegoat" if you have this card active on your side of the field.

If the effect of "Cyber Jar" is activated when you have this card active on your side of the field, monsters that you pick up which could normally be Summoned by the effect of "Cyber Jar" are destroyed instead. Other monsters, such as Level 5 and above monsters, and monsters that can only be Special Summoned, are still added to your hand.

JAM DEFENDER
If you have two "Revival Jams" on the field, you may redirect an attack to either one of your choosing.

If you have "Jam Defender", "Revival Jam", and a monster equipped with your "Ring of Magnetism" on your side of the field, you may redirect an attack to "Revival Jam" when you opponent attacks the monster equipped with "Ring of Magnetism".

JAR ROBBER
You can chain "Jar Robber" to your own or your opponent's "Pot of Greed".

The only way to activate "Jar Robber" is to chain it to the activation of "Pot of Greed".

"Jar Robber" must be the very next step in the chain, so if you activate "Pot of Greed" and your opponent chains "Imperial Order", you cannot activate "Jar Robber".

JENIS, LIGHTSWORN MENDER
"Jenis, Lightsworn Mender's" effect only activates once during the End Phase, even if cards were sent from your Deck to the Graveyard by the effects of multiple "Lightsworn" monsters.

If "Jenis, Lightsworn Mender" is Summoned after card(s) are sent from your Deck to the Graveyard by the effect of a "Lightsworn" Monster, "Jenis, Lightsworn Mender's" effect still activates in the End Phase.

The damage and Life Point gain with "Jenis, Lightsworn Mender" happen at the same time, so it is possible to start a new Chain with "Numinous Healer" or "Attack and Receive", etc.


JETROID
Both players can chain to the Trap Card that is activated by the effect of “Jetroid” (the controller can activate several Trap Cards from his hand in a chain).

If “Ancient Gear Golem” attacks “Jetroid”, the controller of “Jetroid” cannot use its effect.

JINZO
When "Jinzo" is Tribute Summoned, cards like "Trap Hole" and "Torrential Tribute" cannot be activated because "Jinzo's" Continuous Effect is applied when it is Summoned, but you can negate its Summon with "Solemn Judgment", "Horn of Heaven", etc.

If your opponent activates "Waboku" during your Standby Phase and you Summon "Jinzo" in your Main Phase, the effect of "Waboku" is still applied because it resolved before "Jinzo" was Summoned.

If a face-down "Jinzo" is flipped by "Acid Trap Hole", "Jinzo's" effect is not applied if it is destroyed by "Acid Trap Hole".

JINZO - RETURNER
If the Special Summoned "Jinzo" is flipped face-down, it is not destroyed in the End Phase. Even if the "Jinzo" is flipped face-up afterwards, it is not destroyed in the End Phase.

If you send "Jinzo" and "Jinzo - Returner" to the Graveyard at the same time, with "Future Fusion," etc., you can activate the effect of "Jinzo – Returner." If you send multiple copies "Jinzo" and "Jinzo – Returner," the effect of each copy of "Jinzo - Returner" can be activated and will create a Chain (see the rulings for “Simultaneous Effects” in the FAQ).

Destroying "Jinzo" in the End Phase does not start a Chain.

JIRAI GUMO
If a replay occurs when "Jirai Gumo" attacks and you decide to continue attacking with "Jirai Gumo", you do not flip the coin again.

If your opponent has "Toll", you must pay the cost for "Toll" before flipping the coin for "Jirai Gumo"

JOWGEN THE SPIRITUALIST
When playing with this card you need to remember which monsters on the field were Special Summoned because they can later be destroyed with the effect of "Jowgen the Spiritualist". If a monster that was Special Summoned is flipped face-down, it can still be destroyed by the effect of "Jowgen the Spiritualist".

While this card is on the field neither player can activate "Scapegoat", "Monster Reborn", "Call of the Haunted", "Magical Hats", "Dedication through Light and Darkness", or any other card that Special Summons a monster.

If "Jowgen the Spiritualist" is Special Summoned by the effect of "Cyber Jar", all monsters that are Special Summoned by that "Cyber Jar" are Summoned successfully.

JOWLS OF DARK DEMISE
When "Jowls of Dark Demise" is flipped and its effect activates during your opponent's turn, it ends at the end of your opponent's turn. You take control of a monster, but can’t attack with it because it isn’t your turn.

You can take control of a face-down monster with "Jowls of Dark Demise".

You can Tribute a monster you took control of with "Jowls of Dark Demise".
.
If you take control of a Union Monster with "Jowls of Dark Demise", and equip it to your monster, control of the Union Monster Card does not return to your opponent at the end of the turn because it is an Equip Spell Card.

JUDGMENT DRAGON
Paying 1000 Life Points is a cost.

If an effect is chained that flips "Judgment Dragon" face-down, it is not destroyed by its effect.

See “Jain, Lightsworn Paladin” for additional rulings.

JUDGMENT OF ANUBIS
You can activate "Judgment of Anubis" when there are no monsters on your opponent's side of the field.

When you activate "Judgment of Anubis", you destroy your opponent's monster after the activation and the effect of the Spell Care are negated. This means that the monster-destroying effect of "Judgment of Anubis" does not target.

You can activate "Judgment of Anubis" and select a Spell Card that destroys only a Spell Card (like "De-Spell") or only a Trap Card (like "Remove Trap") or could destroy both (like "Mystical Space Typhoon") or many (like "Heavy Storm").

You can activate "Judgment of Anubis" and select a Spell Card that negates the activation of a card and destroys it, like "My Body as a Shield" or "Bait Doll".

You cannot activate "Barrel Behind the Door" against "Judgment of Anubis" because when "Judgment of Anubis" is activated, it has not been confirmed that the damage-inflicting effect will happen.

JUDGMENT OF THE DESERT
You can still change the Battle Positions of monsters with card effects; "Judgment of the Desert" only prevents "manual" changes.

JUDGMENT OF THUNDER
"Judgment of Thunder" cannot be activated in the Damage Step.

"Judgment of Thunder" targets 1 card your opponent controls.

JUNK SYNCHRON
If the monster Special Summoned by "Junk Synchron" is flipped face-down and then face-up, its effects are no longer negated.

If you Special Summon "Nimble Momonga", its effect will activate when it is destroyed by battle and sent to the Graveyard. If you Special Summon "D.D. Scout Plane", its effect will activate when it is removed from play.

If you Special Summon "The Calculator" with "Junk Synchron", you can activate "Inferno Reckless Summon" because "The Calculator's" effect is negated and its ATK is 0.

If you Special Summon "Hand of Nepthys" with "Junk Synchron's" effect, when you activate "Hand of Nephthys'" effect it will be negated, even if you Tribute "Junk Synchron" to activate the effect.

JUTTE FIGHTER
"Jutte Fighter's" effect targets 1 face-up Attack Position monster your opponent controls.

KA-2 DES SCISSORS
The Level of the destroyed monster is the original Level.

You can use "Barrel Behind the Door" against "KA-2 Des Scissors"' effect.

KAHKKI, GUERILLA OF DARK WORLD
This is a Trigger Effect. This effect targets.

KAIBAMAN
Ignition Effects on monsters cannot be activated while the Effect Monster is face-down. So this face-down monster cannot be Tributed for its own effect.

KAISER COLOSSEUM
Your opponent can still Flip Summon a monster.

If there are already more monsters on your opponent's side of the field when you activate "Kaiser Colosseum", nothing happens to your opponent's monsters but your opponent cannot Summon any more. Also, if the number of monsters controlled by "Kaiser Colosseum"'s controller is reduced, the opponent does not have to remove any of his monsters.

Your opponent cannot use "Monster Reborn", "Scapegoat", etc. while "Kaiser Colosseum" prevents him from placing new monsters. However, your opponent CAN use "Change of Heart", "Snatch Steal", etc.

If all monsters of "Kaiser Colosseum"'s controller are destroyed, "Kaiser Colosseum"'s effect no longer functions until that player has at least 1 monster again (when the effect re-activates).

If the player who controls "Kaiser Colosseum" has his only monster taken by the opponent with "Change of Heart", then the opponent can place more monsters because "Kaiser Colosseum"'s effect is no longer active until the player has at least 1 monster again.

When "Kaiser Colosseum" is active, and "Cyber Jar" is activated, if your opponent would control more monsters than you, your opponent has to destroy monsters equal to the difference; the excess monsters are never actually Summoned and instead are sent from the Deck to the Graveyard (so "Witch of the Black Forest" does not get its effect, etc.). So the monsters are destroyed after they are picked up, but before any monsters are Special Summoned for the effect of "Cyber Jar".

While you have "Kaiser Colosseum" on the field, your opponent can Tribute Summon, if after the Summon they will control less or an equal number of monsters as you do.

KAISER GLIDER
The "same ATK" as "Kaiser Glider" means the same as the current ATK, not the original ATK.

When "Kaiser Glider" is in Attack Position and battles a monster with the same ATK, only the other monster is destroyed.

"Kaiser Glider"'s second effect activates when destroyed and sent to the Graveyard from the field, hand, or Deck.

If "Kaiser Glider" is equipped to "Relinquished" or "Thousand-Eyes Restrict", and is destroyed and sent to the Graveyard, "Kaiser Glider"'s effect activates.

KAMINOTE BLOW
The effect of “Kaminote Blow” that destroys monsters at the end of the Damage Step is not part of a chain.

KANGAROO CHAMP
If you attack “Kangaroo Champ” with “Berserk Gorilla” while “Final Attack Orders” is on the field, “Berserk Gorilla” is changed to Defense Position due to “Kangaroo Champ”, and is destroyed by its own effect before it can be changed to Attack Position again.

If “Kangaroo Champ” attacks a Flip Effect Monster, “Kangaroo Champ” is Step 1 of the chain and the Flip Effect Monster is Step 2.

If your opponent’s monster is destroyed during damage calculation then you cannot apply the effect of “Kangaroo Champ”.

The effect of “Kangaroo Champ” can be chained to. After damage calculation, it starts a new chain.


KARATE MAN
"Revese Trap's" effect is not applied because "doubled and halved" are not considered as increasing or decreasing.

If Karate Man is equipped with Megamorph, and Megamorph is halving Karate Man's ATK, and you use Karate Man's effect, Karate Man's ATK is 2000. If you use Karate Man's effect, and THEN equip him with Megamorph after that, and Megamorph would halve his ATK, then his ATK is 500.

If the effect of "Shrink" is applied after "Karate Man's" effect has been used, its ATK will become 500. If "Karate Man" is affected by "Shrink", then its effect is activated, its ATK will become 2000.

KARMA CUT
If “Proto-Cyber Dragon” is removed from play by “Karma Cut”, only other “Proto-Cyber Dragon” cards will be removed from play. “Cyber Dragon” is not affected.

If you target “Harpie Lady 1” with “Karma Cut”, any “Harpie Lady”, “Harpie Lady 1”, “Harpie Lady 2”, “Harpie Lady 3”, or “Cyber Harpie Lady” cards in the opponent’s Graveyard will also be removed from play.

Discarding a card from your hand is a cost to activate “Karma Cut”.

KAZEJIN
A marker may be placed on this card to indicate that its effect has been used. The effect resets if the monster is destroyed or removed from the field.

You can use the effect of this card even if it is face-down when it is attacked because its effect is activated during the Damage Step, and it will be face-up at that point.

The effect of this card targets.

KELDO
You cannot activate "Keldo"'s effect when there are not at least 2 cards in your opponent's Graveyard.

The owner of the Deck shuffles it and the controller of "Keldo" cuts the Deck.

KID GUARD
This card must be activated when the opponent's monster declares an attack.

KING DRAGUN
The first effect of “King Dragun” is a Continuous Effect. The second effect of “King Dragun” is an Ignition Effect.

Your opponent cannot target a Dragon-Type Fusion Monster with “De-Fusion” while “King Dragun” or “Lord of D.” is on the field because “De-Fusion” targets.

“Divine Wrath” is NOT a card that targets, so “Divine Wrath” may be used against Dragon-Type monsters while “King Dragun” or “Lord of D.” is on the field.

You can chain “Divine Wrath” to the effect of “King Dragun” that Special summons a Dragon-Type monster.


KING OF THE SKULL SERVANTS
If the number of “Skull Servant” and “King of the Skull Servants” cards in your Graveyard changes, re-calculate the original ATK of “King of the Skull Servants”. If it is equipped with "Megamorph" you would then re-apply the effect of "Megamorph".

If you have 2 "Skull Servant" cards in your Graveyard (original ATK 2000), and you equip this card with "Megamorph", its current ATK will become either 4000 or 1000, depending on your Life Points.

Since the ATK of this card is ?, it cannot be Special Summoned by the effect of "Mystic Tomato".

Removing from play 1 “Skull Servant” or “King of the Skull Servants” to Special Summon a “King of the Skull Servants” is a cost.


KING OF THE SWAMP
You can only get 1 copy of "Polymerization" when you discard "King of the Swamp" from your hand.

You can activate the effect of "King of the Swamp" even if all 3 of your "Polymerization" cards are in your Graveyard.

If "King of the Swamp" is selected for the effect of "Prohibition", you cannot use either of its effects.

Discarding this card is a cost.

If you use "King of the Swamp" as Fusion Material from your hand, you do not get to activate its effect to search your Deck for "Polymerization".

KING TIGER WANGHU
Monsters with ATK 1400 or less that are already on the field when "King Tiger Wanghu" is Summoned are not destroyed. "King Tiger Wanghu"’s effect only applies to monsters Summoned while it is face-up on the field.

When a monster is Flip Summoned or flipped face-up by a card effect, it is not destroyed by the effect of "King Tiger Wanghu".

"King Tiger Wanghu"’s effect applies to both sides of the field.

When "King Tiger Wanghu" is Special Summoned by the effect of "Cyber Jar", other monsters with ATK 1400 or less that are Special Summoned by the same "Cyber Jar" are destroyed if they are Special Summoned in face-up Attack Position.

If a monster’s ATK when it is Summoned is less than 1400 due to the effect of other cards, such as a Field Spell Card that reduces its ATK, it is destroyed by "King Tiger Wanghu"’s effect (so apply all existing modifiers before determining if the monster is destroyed). If "Command Knight" is Summoned, it increases its own ATK to 1600 before "King Tiger Wanghu" can destroy it.

If "King Tiger Wanghu" is Normal Summoned or Special Summoned, and its own ATK is reduced below 1400 by a pre-existing effect, then it destroys itself when Summoned. (Example: "King Tiger Wanghu" and "Bladefly" are Special Summoned simultaneously by "Cyber Jar". "King Tiger Wanghu"’s ATK is 1300, and it is destroyed by its own effect (and "Bladefly" is also destroyed by "King Tiger Wanghu"’s effect).

Monsters that are Summoned face-down (like with "The Shallow Grave") are not destroyed by King Tiger Wanghu.

"King Tiger Wanghu"’s effect includes Monster Tokens with ATK 1400 or less.

If "King Tiger Wanghu" is on the field and "Marauding Captain" is Summoned, "Marauding Captain" can still activate its effect and Special Summon a monster even though "Marauding Captain" is destroyed.

If "King Tiger Wanghu" is on the field along with Trigger Effect monsters such as "Mysterious Puppeteer", "Ryu-Kishin Clown", "Sonic Bird", and "Dragon Seeker", then they form a chain.

If "King Tiger Wanghu" is on the field, and "Exiled Force" is Summoned, "King Tiger Wanghu"’s effect immediately activates. Since "Exiled Force" cannot be chained, "King Tiger Wanghu" will destroy "Exiled Force" before the turn player can Tribute "Exiled Force" using its effect.

KING'S KNIGHT
When “King’s Knight” is Normal Summoned, its Trigger Effect starts a chain if “Queen’s Knight” is on the field. If the opponent chains “Torrential Tribute” to destroy “King’s Knight” and “Queen’s Knight” you still Special Summon “Jack’s Knight”.

The effect of “King’s Knight” can only activate if it is Normal Summoned. Not if it is Flip Summoned, Special Summoned, or Set.

KINKA-BYO
"Kinka-Byo's" effect targets 1 Level 1 monster in your Graveyard and continues to target it while it is on the field.

Removing the Special Summoned monster from play when "Kinka-Byo" is removed from the field does not start a Chain.

When "Kinka-Byo" is flipped face-down its effect disappears. If it is flipped face-up and Special Summons another Level 1 monster, when it is removed from the field only the newly Special Summoned Level 1 monster is removed from play. The previously Special Summoned Level 1 monster remains on the field.

If you Special Summon "Arcana Force 0 - The Fool" with "Kinka-Byo's" effect and the coin toss for "Arcana Force 0 - The Fool" is heads, "Kinka-Byo's" effect is negated and it is destroyed. "Arcana Force 0 - The Fool" remains on the field.

KIRYU
While "Mask of Restrict" is active, you cannot Tribute "Kiryu" because "Mask of Restrict" prevents all Tributing, including Tributing Equip Spell Cards.

If you Tribute "Kiryu" while it is equipped to "Dark Blade", you cannot then use "Super Rejuvenation" and count "Kiryu" as a Dragon-Type monster.

If you Tribute "Kiryu" while equipped to "Dark Blade", "Dark Blade" no longer gets the ATK increase from "Kiryu" as it is no longer equipped with it.

KISHIDO SPIRIT
If your monster in Defense Position is attacked by a monster with equal ATK to your monster's ATK, your Defense Position monster will not be destroyed even if its DEF was lower than the attacking monster's ATK.

When "Spear Dragon" attacks a Defense Position monster with equal ATK to "Spear Dragon", perform damage calculation normally even though the Defense Position monster is not destroyed.

KOITSU
"Koitsu"'s effect that inflicts damage is only applied to a monster that is equipped with "Koitsu" by "Koitsu"'s effect; "Koitsu" itself, while a monster, does not receive this effect.

KOTODAMA
Sheep Tokens will be destroyed by the effect of "Kotodama" since Monster Tokens are considered cards.

If two Flip Effect monsters are flipped face-up at the same time while "Kotodama" is on the field, their effects are negated and they are destroyed.

If 2 or more monsters with identical names are on the field when "Kotodama" is Summoned, they are all destroyed.

KOZAKY'S SELF-DESTRUCT BUTTON
You cannot activate “Kozaky’s Self-Destruct Button” because it has no activation effect.

If “Bait Doll” targets “Kozaky’s Self-Destruct Button”, nothing happens because the timing is inappropriate. However, “Kozaky’s Self-Destruct Button” is then destroyed by “Bait Doll”.

“Kozaky’s Self-Destruct Button” starts a chain at the time that it is sent to the Graveyard. If “Banisher of the Light” is on the field and “Kozaky’s Self-Destruct Button” is removed from play, its effect still activates because it only has to be destroyed.

KREBONS
Paying 800 Life Points is a cost. "Krebons'" effect does not target.

If "Asura Priest" attacks "Krebons" and "Krebons'" effect is used to negate the attack, "Asura Priest" cannot attack that same "Krebons" again during the same Battle Phase.

If an effect is chained that flips "Krebons" face-down, its effect still resolves and the attack is still negated.

KRYUEL
If "Second Coin Toss" is active, and "Kryuel" is sent to the Graveyard as a result of battle, you can re-do the coin toss.

KUNOICHI
If an effect is chained that removes "Kunoichi" from the field, its new controller still discards 1 card.

If you give control of your face-up "Kunoichi" to your opponent while "Remove Brainwashing" is active, it is immediately returned to your control and when its effect resolves you will discard 1 card.

KURIBOH
"Kuriboh" does not target the attacking monster.

"Kuriboh" only prevents Battle Damage to your Life Points; it will not prevent your monsters from being destroyed.

"Kuriboh" can only be activated while in your hand, its effect cannot be used while "Kuriboh" is on the field.

"Kuriboh's" effect is a Quick Effect.

"Kuriboh" is activated during damage calculation. If your opponent attacks with "Injection Fairy Lily" and activates her effect, you can chain "Kuriboh" to reduce the damage to zero.
