Leviamon

All Turns Once Per Turn When an opponent's Digimon or one of your Seven Great Demon Lords trait Digimon is played, by trashing 1 card in your hand, return the bottom 3 digivolution cards of 1 of your opponent's Digimon to the bottom of the deck. Then, if they have as many or fewer total Digimon and Tamers as you, delete 1 of their Digimon with no digivolution cards.

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.
