Pandemonium
Card effect (current official text)Neither player has to pay Life Points during the Standby Phase for "Archfiend" monsters. Each time a player's "Archfiend" monster(s) is destroyed and sent to the Graveyard, except by battle, that player can add 1 "Archfiend" monster from their Deck to their hand that is a lower Level than the destroyed card.
Rulings
- You can't use Pandemonium to add a Fusion Monster Archfiend or Synchro Monster Archfiend from the Extra Deck to your hand, like Fiend Skull Dragon or Red Dragon Archfiend.
- If multiple Archfiends are destroyed at the same time by Raigeki, you can only add 1 Archfiend from your Deck to your hand with Pandemonium.
- When your Archfiends controlled by your opponent are sent to your GY, you can add an Archfiend from your Deck to your hand with Pandemonium.
