This card cannot be Special Summoned. You can Normal Summon this card with 1 Tribute. If you do, it becomes Level 5 and its original ATK and DEF are halved.
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.
As long as this card remains face-up on your side of the field, "Pandemonium" on your side of the field is not destroyed by your opponent's card effects.
During the Main Phase: Fusion Summon 1 "Prank-Kids" Fusion Monster from your Extra Deck, using monsters from your hand or field as Fusion Material. For the rest of this turn after this card resolves, you cannot Normal or Special Summon monsters, except "Prank-Kids" monsters.
