[[Digivolve] [Belphemon: Sleep Mode]: Cost 1]
[On Play] [When Digivolving] You may trash up to 3 cards in your hand. For each one, suspend 1 of your opponent's level 5 or lower Digimon. Then, delete all of their lowest play cost suspended Digimon.
[All Turns] When this Digimon would leave the battle area other than by battle, place 1 [Seven Great Demon Lords] trait card from your trash as the bottom digivolution card of your [Gate of Deadly Sins] in the breeding area.
