COTD-JP001 Cyberse Wizard

Q: Can I activate the effect of Cyberse Wizard during my Main Phase 2?
A: You can activate the effect of Cyberse Wizard during your Main Phase 2. (You can do so even if you already attacked monsters other than the monster that you target.) In that case, the effect only changes the targeted monster to Defense Position.

Q: I activate the effect of Cyberse Wizard, targeting my opponent’s Cracking Dragon. If my opponent chains Compulsory Evacuation Device, and returns Cyberse Wizard to the hand, how does its resolve?

Q: I activate the effect of Cyberse Wizard, targeting my opponent’s Cracking Dragon. If my opponent chains Compulsory Evacuation Device, and returns Cracking Dragon to the hand, how does the effect of Cyberse Wizard resolve?
A: In this scenario, the Cracking Dragon targeted with the effect of Cyberse Wizard has returned to the hand by the time the effect resolves, so it cannot be changed to Defense Position. In that case, the parts of the effect that prevent your monsters from attacking except to attack that target, and that allow your Cyberse-Type monsters to inflict piercing battle damage, are not applied.

Q: I activate the effect of Cyberse Wizard, targeting my opponent’s Cracking Dragon and changing it to Defense Position. During the Battle Phase of this turn, if my opponent activates Compulsory Evacuation Device and returns Cracking Dragon to the hand, can my Cyberse Wizard still attack?
A: In this scenario, due to the effect of Cyberse Wizard, it is not possible for monsters on your field to attack monsters other than the targeted Cracking Dragon, and they cannot attack directly. Therefore, since the targeted Cracking Dragon was returned to the hand, Cyberse Wizard cannot attack.

Q: I activate the effect of Cyberse Wizard, targeting my opponent’s Cracking Dragon and changing it to Defense Position. During the same turn, if I Special Summon a Backup Secretary by its own effect, how will it be able to attack during the Battle Phase?
A: In this scenario, after the effect of Cyberse Wizard resolves, it is applied to all monsters/Cyberse-Type monsters on your field during this turn. Therefore, the newly Special Summoned Backup Secretary cannot attack unless it attacks the targeted Cracking Dragon, but it will also inflict piercing battle damage to your opponent.

Q: Hack Worm and Jack Wyvern are face-up on my opponent’s field in Attack Position. In this situation, I activate the effect of Cyberse Wizard, and change Jack Wyvern to Defense Position. During the same turn, if I also have a Paladin of Felgrand on my field equipped with United We Stand, how will it be able to attack during the Battle Phase?
A: In this scenario, due to the effect of Cyberse Wizard, monsters on your field cannot attack unless they attack the targeted Jack Wyvern. However, since Paladin of Felgrand is unaffected by other monsters’ effects while equipped with an Equip Card, it is unaffected by the effect of Cyberse Wizard and can also attack Hack Worm.

COTD-JP003 Stack Reviver

Q: I activate Mimiclay, targeting a face-up Defense Position Stack Reviver on my field, and Special Summon another Stack Reviver from my Deck. If I Link Summon a Honeybot using both copies of Stack Reviver as Link Materials, can I activate the effect of a Stack Reviver?
A: In this scenario, the Stack Reviver that was Special Summoned from the Deck by the effect of Mimiclay will be banished instead of sent to the Graveyard when used as a Link Material for a Link Summon. Even in that case, you can activate the effect of that banished Stack Reviver. (The other Stack Reviver that was used as a Link Material to Link Summon Honeybot can be targeted with the effect.)

COTD-JP004 Launcher Commander

Q: Skill Drain is face-up on the field, and the effects of all face-up monsters on the field are negated. In this situation, if I activate the effect of Launcher Commander, will it be negated?
A: While the effect of Skill Drain is applying, if you activate the effect of Launcher Commander by Tributing that same Launcher Commander, the effect will not be negated and resolves normally. If you activate the effect of Launcher Commander by Tributing a different Cyberse-Type monster, the effect is negated by Skill Drain and the targeted monster is not destroyed.

COTD-JP005 Salvegent Driver

Q: Decode Talker and Salvegent Driver are face-up on my field. In this situation, when my Decode Talker declares an attack, my opponent activates Mirror Force and destroys both Decode Talker and Salvegent Driver. At this time, can I activate the effect of Salvegent Driver that Special Summons it from the Graveyard?
A: The effect of Salvegent Driver can be activated when a Cyberse-Type Link Monster on your field is destroyed by your opponent’s card while it is already present in your hand or Graveyard. Therefore, in this scenario, you cannot activate the effect of Salvegent Driver because it was destroyed by your opponent’s card effect at the same time as your Cyberse-Type Link Monster.

In this situation, if my opponent activates Mystical Space Typhoon and destroys the equipped Firewall Dragon, can I activate the effect of Salvegent Driver that Special Summons it from my hand or Graveyard?
A: As in this scenario, if a Cyberse-Type Link Monster on your field is destroyed by your opponent’s card while treated as an Equip Card, you cannot activate the effect of a Salvegent Driver in your hand or Graveyard.

Q: When I Normal or Flip Summon a Trickstar Lilybell, my opponent activates Forced Back, negates the Summon, and returns Trickstar Lilybell to my hand. Afterward, can I activate the effect of Trickstar Lilybell that Special Summons it if is added to the hand?
A: Even in this scenario, Trickstar Lilybell was added to your hand by a method other than drawing, so you can activate its effect that Special Summons it.

COTD-JP007 Trickstar Lycorissica

Q: If the effect of my opponent’s The Eye of Truth is applying, can I activate the effect of a Trickstar Lycorissica in my hand?
A: If your hand is revealed by the effect of The Eye of Truth, you cannot activate the effect of a Trickstar Lycorissica in your hand.

Q: If Trickstar Lycorissica is in my hand, can I activate its effect that Special Summons it more than once on the same Chain?
A: If there are multiple copies of Trickstar Lycorissica in your hand, you can activate each of their effects that Special Summon them from your hand. However, Trickstar Lycorissica must be revealed in your hand to activate its effect, and remains revealed until the effect resolves, so a single Trickstar Lycorissica can only activate its effect once in a Chain.

Q: During my turn, my opponent activates Call of the Haunted and Special Summons a Dino-Sewing from their Graveyard with 0 ATK. In this case, if Cracking Dragon was face-up on my field, can I activate its effect?
A: Even in this scenario, since your opponent Special Summoned 1 monster, you can activate the effect of Cracking Dragon. Dino-Sewing is a Level 4 monster, so the effect of Cracking Dragon will make it lose ATK equal to its Level × 200, which is 800. However, since Dino-Sewing has 0 ATK, your opponent takes no damage. Also, if you attack Dino-Sewing with Cracking Dragon this turn, Dino-Sewing will gain 1000 ATK and DEF, but since the effect of Cracking Dragon was applied, its resulting ATK will be 200.

Q: When my opponent Normal Summons a Stack Reviver, I activate the effect of Cracking Dragon. In this case, how much damage is inflicted to my opponent?
A: In this scenario, since Stack Reviver is a Level 2 monster, the effect of Cracking Dragon will make it lose ATK equal to its Level × 200, which is 400. However, since Stack Reviver is a monster with 100 ATK, it only loses that 100 ATK, and the damage inflicted to your opponent is also 100.

In this case, if Dinomist Rex inflicts battle damage to my opponent while unaffected by other cards’ effects, will the effect of Supreme King Servant Odd-Eyes double that damage?
A: The effect of Supreme King Servant Odd-Eyes that doubles battle damage inflicted by Pendulum Monsters on your field is not an effect that is applied to those monsters. In this scenario, the battle damage inflicted to your opponent by Dinomist Rex, which was Special Summoned by the effect of Dinomist Rush, is still doubled.

COTD-JP053 Trickstar Lightstage

Q: I activate the effect of Trickstar Lightstage, targeting a Set card in my opponent’s Spell & Trap Zone. If the targeted card is Dark World Brainwashing, and my opponent chains it, how does the effect of Trickstar Lightstage resolve?
A: If the card targeted with the effect of Trickstar Lightstage is chained and becomes face-up, the effect of Trickstar Lightstage is not applied. (In this scenario, the effect of Dark World Brainwashing can be activated during this turn, also it is not sent to the Graveyard during the End Phase.)

Q: I activated and resolved the effect of Trickstar Lightstage, so that the targeted Set card in my opponent’s Spell & Trap Zone cannot be activated until the End Phase. If my opponent activates a Mystical Space Typhoon and destroys Trickstar Lightstage, what happens to that Set card?
A: If Trickstar Lightstage is destroyed after applying its effect, the effect is no longer applied. The targeted card can now be activated normally, and it is not sent to the Graveyard during the End Phase if it is not activated at that time.

Q: While Trickstar Lightstage is face-up in my Field Zone, a Trickstar Lilybell on my field attacks directly with its effect and inflicts battle damage to my opponent. At this time, does the effect of Trickstar Lightstage inflict 200 damage to my opponent?
A: If a “Trickstar” monster inflicts battle damage to your opponent, the effect of Trickstar Lightstage inflicts damage to your opponent immediately after damage calculation. In this scenario, the effect is immediately applied after damage calculation, then you can choose to activate the effect of Trickstar Lilybell that adds a “Trickstar” monster in your Graveyard to your hand.

COTD-JP055 Aircrack Storm

Q: My Cracking Dragon equipped with Aircrack Storm destroys an opponent’s monster by battle, and I activate the effect of Aircrack Storm that allows the equipped monster to attack a second time during this Battle Phase. When Cracking Dragon attacks a second time, what happens to the attack if my opponent activates Mystical Space Typhoon and destroys Aircrack Storm?
A: After the effect of Aircrack Storm is applied, if Aircrack Storm is no longer equipped when your monster is attacking a second time, it is no longer able to make a second attack. In this scenario, if Aircrack Storm was destroyed during the Battle Step before you declared the second attack with Cracking Dragon, Cracking Dragon cannot declare another attack. Also, if Aircrack Storm was destroyed during the Battle Step after the second attack was declared, the attack stops without continuing to damage calculation.

Q: I have 2 copies of Cracking Dragon on my field, and 1 is equipped with Aircrack Storm. My Cracking Dragon equipped with Aircrack Storm destroys an opponent’s monster by battle, and I activate the effect of Aircrack Storm that allows the equipped monster to attack a second time during this Battle Phase. If Aircrack Storm is then destroyed by Mystical Space Typhoon, can my other Cracking Dragon attack during this Battle Phase?
A: During the turn you activate the effect of Aircrack Storm, monsters other than the equipped monster cannot attack. Even if Aircrack Storm is subsequently destroyed, that restriction is still applied and your other monsters cannot attack. In this scenario, after Aircrack Storm is destroyed, your other Cracking Dragon cannot attack.

My Cracking Dragon equipped with Aircrack Storm destroys an opponent’s monster by battle, and I activate the effect of Aircrack Storm that allows the equipped monster to attack a second time during this Battle Phase. During this Battle Phase, if Tailor of the Fickle is activated and equips Aircrack Storm to my other Cracking Dragon, can that one attack?
A: During the turn you activate the effect of Aircrack Storm, monsters other than the equipped monster cannot attack. Therefore, in this scenario, even if Aircrack Storm is equipped to a different monster by the effect of Tailor of the Fickle, the newly equipped Cracking Dragon cannot attack.

Q: A Cracking Dragon affected by Forbidden Lance and a Jack Wyvern equipped with Aircrack Storm are both face-up on my field. When Jack Wyvern attacks and destroys an opponent’s monster by battle, I activate the effect of Aircrack Storm that allows the equipped monster to attack a second time during this Battle Phase, but prevents my other monsters from attacking. During this Battle Phase, can I still attack with Cracking Dragon?
A: During the turn you activate the effect of Aircrack Storm, monsters other than the equipped monster cannot attack. This is not treated as part of the effect of Aircrack Storm, so even if the effect of Forbidden Lance makes Jack Wyvern unaffected by Spell effects, it cannot attack during this Battle Phase.

Q: Encounter with the Starrelic is face-up in my Field Zone.

A: Even if a “Stargrail” Link Monster is destroyed by battle or leaves the field because of your opponent’s card effect, you can activate the effect of Encounter with the Starrelic. However, you cannot target a “Stargrail” Link Monster with that effect, so you must have an appropriate “Stargrail” monster in your Graveyard to target.

Q: Can I activate March of the Night Brigade by targeting a Michael, the Arch-Lightsworn in my Graveyard?
A: You can activate March of the Night Brigade by targeting a Michael, the Arch-Lightsworn in your Graveyard. (Since Michael, the Arch-Lightsworn is a Level 7 monster, it can only be targeted if you have 7 or more cards in your Deck.) In this case, since Michael, the Arch-Lightsworn is a Synchro Monster, it returns to your Extra Deck instead of your hand, and you do not banish any cards from the top of your Deck afterward.

Q: Spellbook Magician of Prophecy is Set in my Monster Zone. When resolving the effect of Spellbook of Rudra, can I choose that Set Spellbook Magician of Prophecy as the Spellcaster-Type monster that is sent to the Graveyard?
A: The effect of Spellbook of Rudra sends 1 “Spellbook” Spell Card that is either face-up on your field or in your hand to the Graveyard, or 1 face-up Spellcaster-Type monster from your field to the Graveyard. (You cannot send Spellcaster-Type monsters that are face-down on the field, nor “Spellbook” Spell Cards that are Set in your Spell & Trap Zones.) In this case, if there are no appropriate cards you can send to the Graveyard, you cannot activate Spellbook of Rudra.

A: Even in this scenario, when resolving the effect of Spellbook of Rudra, you can choose a White Wing Magician on your field as the card to send to the Graveyard.

A: The effect of Castle Link moves 1 targeted Link Monster to a Main Monster Zone linked to it. (It cannot be moved to an Extra Monster Zone.)

A: When resolving the effect of Castle Link, if control of the targeted Link Monster is changed by an Enemy Controller that was chained to the effect, the effect of Castle Link resolves normally. In this scenario, after Honeybot changes control, you still move it to an adjacent Main Monster Zone that is linked to it.

If my opponent chains Compulsory Evacuation Device and returns Stargrail Dragon Imduk to the Extra Deck, how does the effect of Castle Link resolve?
A: In this scenario, since Stargrail Shrine Maiden Eve is the only Link Monster in your Main Monster Zone when the effect of Castle Link resolves, the effect cannot be applied. (Stargrail Shrine Maiden Eve remains where it is in its Main Monster Zone.) At this time, if there are 2 Link Monsters in your opponent’s Main Monster Zones, the effect still applies and switches them.

In this situation, I activate the second effect of Castle Link that switches the Zones of 2 Link Monsters on the same side of the field.

A: In this scenario, since there are 2 Link Monsters in the Main Monster Zones, those are the 2 that are chosen when the effect of Castle Link resolves. However, since Stargrail Dragon Imduk is unaffected by Spell effects, you cannot move it to another Zone. (Both Stargrail Shrine Maiden Eve and Stargrail Dragon Imduk remain where they are in their Main Monster Zones.)

COTD-JP066 Defense Zone

Q: Defense Zone is face-up in my Field Zone. U.A. Playmaker is face-up in my Main Monster Zone, and U.A. Powered Jersey is face-up in my Spell & Trap Zone of the same column. Also, U.A. Blockbacker is face-up in my opponent’s Main Monster Zone, and U.A. Penalty Box is face-up in the opponent’s Spell & Trap Zone of the same column. In this case, which cards in the Spell & Trap Zones cannot be targeted or destroyed by which player’s effects?
A: The effect of Defense Zone is one that prevents cards in a player’s Spell & Trap Zone from being targeted or destroyed by their opponent’s card effects, as long as they are in the same column as a monster in that player’s Main Monster Zone. Therefore, in this scenario, the U.A. Powered Jersey on your field cannot be targeted or destroyed by your opponent’s card effects, while the U.A. Penalty Box on your opponent’s field cannot be targeted or destroyed by your card effects. (The result is the same even if Defense Zone is face-up in your opponent’s Field Zone instead.)

In other words, even if both players have Defense Zone in their respective Field Zones, there is no difference in how the effect is applied.

A: If you activate 2 copies of Three-Strike Barrier in the same turn, you can select the third effect for both of them. In that case, when a monster on your field inflicts battle damage to your opponent, each effect is applied.

Q: A Supreme King Servant Starving Venom that was first Fusion Summoned is in my Graveyard. In this situation, if I activate Wrath of the Supreme King, can I Special Summon that Supreme King Servant Starving Venom from the Graveyard?
A: Supreme King Servant Starving Venom is a monster that can only be Special Summoned by Fusion Summon or by its other written procedure, and cannot be Special Summoned from the Graveyard afterward with effects such as Monster Reborn. However, since the effect of Wrath of the Supreme King ignores the Summoning conditions written in its text, a Supreme King Servant Starving Venom that was previously properly Special Summoned by Fusion Summon or its other written procedure can be Special Summoned.

In this situation, if I activate Wrath of the Supreme King, can I Special Summon those monsters from the Graveyard?
A: Fusion, Synchro, and Xyz Monsters sent directly from the Extra Deck to the Graveyard by the effect of Zaborg the Mega Monarch were never properly Special Summoned. Therefore, in this scenario, Supreme King Servant Starving Venom, Supreme King Servant Clear Wing, and Supreme King Servant Dark Rebellion cannot be Special Summoned from the Graveyard with the effect of Wrath of the Supreme King.

A: When resolving the effect of Dark World Brainwashing, if Dark World Brainwashing itself has been destroyed, the effect is not applied. (Grapha, Dragon Lord of Dark World remains on the field, and the effect of Ryko, Twilightsworn Fighter banishes 1 card on the field normally.)

Q: My opponent activates the effect of Master Peace, the True Dracoslaying King that destroys 1 other card on the field, while it is also unaffected by monster and Trap effects as a result of being Tribute Summoned by Tributing a monster and a Continuous Trap Card.

A: The effect of Dark World Brainwashing is not treated as one that affects the monster activating its effect. In this scenario, the effect of Master Peace, the True Dracoslaying King changes from “Destroy (the targeted card)” to “Discard 1 random card from your opponent’s hand.”

COTD-JP075 Breakdown Trap Hole

Q: Mystery Shell Dragon is in my Main Monster Zone in the same column as the Extra Monster Zone, and Galaxy Serpent is in a Main Monster Zone adjacent to it. In this scenario, if I Link Summon a Link Spider to my Extra Monster Zone using Galaxy Serpent, can my opponent activate Breakdown Trap Hole?
A: In this scenario, when Link Spider is Link Summoned, Mystery Shell Dragon becomes linked to it. Breakdown Trap Hole can be activated when a monster is Link Summoned, and the effect destroys all monsters on the field that are not linked. In this scenario, since the only monsters on the field are linked, Breakdown Trap Hole cannot be activated.

Q: While there are no monsters on my opponent’s field, I activate Monster Reborn and Special Summon a Honeybot to my center Main Monster Zone, while Bittron and Backup Secretary are in the Main Monster Zones adjacent to it on the left and right, respectively. If I Link Summon a Stargrail Dragon Imduk to the left Extra Monster Zone using Bittron as Link Material, and my opponent activates Breakdown Trap Hole, which monsters on the field are destroyed?
A: Breakdown Trap Hole can be activated when a monster is Link Summoned, and the effect destroys all monsters on the field that are not linked. (When the effect resolves, monsters that are linked to Link Monsters other than the one that was Special Summoned are not destroyed.) In this scenario, Honeybot and Backup Secretary are linked, but Stargrail Dragon Imduk does not have a link with any other monster, so only Stargrail Dragon Imduk is destroyed.

A: In this scenario, since Master Peace, the True Dracoslaying King is unaffected by Trap Cards, the activation of its effect is not negated by Recall and it is not destroyed, so its effect destroys the targeted card normally. Even in that case, your opponent draws 1 card.

COTD-JP079 Blind Ruination

Q: If the only face-up monsters on the field are Level/Rank 12 monsters, such as Supreme King Z-ARC or Number 77: The Seven Sins, can Blind Ruination be activated?
A: Blind Ruination destroys monsters whose Levels/Ranks are lower than the added result of the 2 die rolls, which means the highest possible total of 12 will only destroy face-up Level/Rank 11 or lower monsters on the field, and Level/Rank 12 monsters can never be destroyed by this effect. Therefore, if the only face-up monsters on the field are Level/Rank 12, you cannot activate Blind Ruination.

Q: If the only face-up monsters on the field are Link Monsters, can Blind Ruination be activated?

Q: If my opponent activates Blind Ruination, can I chain My Body as a Shield?
A: Since it is unknown whether or not the effect of Blind Ruination will destroy monsters on the field until it resolves, you cannot normally chain My Body as a Shield to it. However, if there are any Level/Rank 1 monsters on the field, they will be destroyed regardless of the outcome of the die rolls. In that case, the effect of Blind Ruination is considered one that would destroy a monster on the field, and My Body as a Shield can be chained.

COTD-JP080 Transmission Gear

Q: If the effects of Imperial Iron Wall or Chaos Hunter prevent me from banishing cards, can I activate Transmigration Gear?

Q: A Geargiano Mk-III is face-on my opponent’s field, and it is unaffected by Spell/Trap effects due to the effect of Forbidden Lance. In this situation, if Transmission Gear is activated during damage calculation when Geargiano Mk-III battles my Geargiano Mk-II, what happens if I win the rock-paper-scissors game?
A: The effect of Transmission Gear makes the losing player banish their battling monster face-down, and is not an effect that is applied to the battling monster, so even in this case your opponent must banish their Geargiano Mk-III.

Q: My opponent’s Geargiano attacks a Geargiano Mk-II on my field. During damage calculation, if I activate Transmission Gear, but my opponent chains their own Transmission Gear, what happens?
A: In this scenario, when resolving the effect of Transmission Gear that was activated as Chain Link 2, the player who loses the game of rock-paper-scissors must banish their battling monster face-down, so either the opponent’s Geargiano or your Geargiano Mk-II is banished. When resolving the Transmission Gear that was activated as Chain Link 1, since no monsters are currently battling, the effect is not applied. (Players do not play another game of rock-paper-scissors, and no monster is banished face-down.)
