Mortuary + Vein Ripper + Carrion Feeder + Gwenom, Remorseless

Mortuary

Vein Ripper

Carrion Feeder

Gwenom, Remorseless

How it works

1. Activate Carrion Feeder by sacrificing it.
2. When Carrion Feeder dies, Mortuary and Vein Ripper trigger.
3. Resolve the Mortuary trigger, putting Carrion Feeder from your graveyard onto the top of your library.
4. Resolve the Vein Ripper trigger, causing you to gain 2 life and target opponent to lose 2 life.
5. Resolve the Carrion Feeder ability.
6. Cast Carrion Feeder from the top of your library by paying 1 life.
7. Repeat.

This clever loop turns Carrion Feeder into an endless engine of sacrifice by leveraging Mortuary to recycle the creature straight to the top of your library whenever it hits the graveyard. Gwenom, Remorseless then breaks the casting restriction wide open, letting you replay that freshly stacked Carrion Feeder directly from the library while substituting its mana cost with a small payment of life. Meanwhile, Vein Ripper passively sits back and converts every single iteration of this grim cycle into guaranteed, game-ending life drain for your opponents.
