Demise, Supreme King of Armageddon

DARKRitual/Effect Monster

You can Ritual Summon this card with "Cycle of the World". This card’s name becomes "Demise, King of Armageddon" while in the hand or on the field. Ritual Monsters you control cannot be destroyed by battle. If this card was Ritual Summoned using only Ritual Monsters, you do not pay LP to activate this card’s effects. Once per turn: You can pay 2000 LP; destroy as many other cards on the field as possible, and if you do, inflict 200 damage to your opponent for each of their cards destroyed by this effect.
