Hellbreak Emissary

Flying

Whenever you defile, put the bottom card of your
library into your graveyard. (Whenever a creature
you control dies, you discard a card, or you mill a
card for the first time each turn, you defile.)

Sacrifice Hellbreak Emissary: Return target creature
card from your graveyard to your hand. If you
defiled three times this turn, return that card to the battlefield tapped instead.
