Desrook Archfiend
Card effect (current official text)The controller of this card pays 500 Life Points during each of his/her Standby Phases (this is not optional). When this card is targeted by the effect of a card controlled by your opponent, when resolving the effect, roll a six-sided die. If the result is 3, negate the effect and destroy the opponent's card. When a "Terrorking Archfiend" on your side of the field is destroyed and sent to the Graveyard, you can send this card from your hand to the Graveyard to Special Summon the "Terrorking Archfiend".
Rulings
- Missing the Timing: Because Desrook Archfiend's effect is optional, the Terrorking Archfiend being sent to the GY has to be the very last thing that happened in order for you to activate Desrook Archfiend's effect. You cannot activate Desrook Archfiend's effect in the middle of a chain, such as if Pot of Greed was activated and Ring of Destruction was chained to destroy Terrorking Archfiend and send him to the GY in the middle of the chain.
- You can activate Desrook Archfiend's effect when a face-down Terrorking Archfiend is destroyed and sent to the GY by a card effect.
- Desrook Archfiend is a Multi-Trigger Effect and can be activated during your opponent's turn, and even during the Damage Step.
- When you control your opponent's Terrorking Archfiend with Change of Heart, and it is destroyed, you can activate Desrook Archfiend from your hand to Special Summon the Terrorking Archfiend back to your side of the field.
- While Pandemonium is applying, and you have Desrook Archfiend in your hand, and your Terrorking Archfiend is destroyed while on the field, Pandemonium is Step 1 of a chain , but you can use Desrook Archfiend as Step 2 of the chain. Then you would get to Special Summon the Terrorking Archfiend and select a Lv 3 or lower Archfiend from your Deck.
- Q: If I activate the effect of "Desrook Archfiend" to revive my "Terrorking Archfiend" who died in battle, can I use the effect of a "Pandemonium" since "Desrook Archfiend" went to the GY? A: No, "Desrook Archfiend" wasn’t destroyed and sent to the GY, it was just sent to the GY. 01/15/04
