Leviamon

[All Turns] [Once Per Turn] When an opponent's Digimon or one of your Digimon with the [Seven Great Demon Lords] trait 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 your opponent has as many or fewer total Digimon and Tamers as you, delete 1 of your opponent's Digimon with no digivolution cards.
[All Turns] When this Digimon would leave the battle area other than in battle, place 1 card with the [Seven Great Demon Lords] trait from your trash as the bottom digivolution card of one of your [Gate of Deadly Sins] in your breeding area.
