Mortuary + Bile Urchin + Proper Burial + Gwenom, Remorseless

Mortuary

Bile Urchin

Proper Burial

Gwenom, Remorseless

How it works

1. Activate Bile Urchin by sacrificing it.
2. When Bile Urchin dies, Mortuary and Proper Burial trigger.
3. Resolve the Mortuary trigger, putting Bile Urchin from your graveyard onto the top of your library.
4. Resolve the Proper Burial trigger, causing you to gain 1 life
5. Resolve the Bile Urchin ability.
6. Cast Bile Urchin from the top of your library by paying 1 life.
7. Repeat.

This loop turns a humble goblin into an infinite engine of life and decay by exploiting a clever replacement effect from Mortuary, which constantly recycles sacrificed creatures straight back to the top of your library. Gwenom, Remorseless is the linchpin that makes this recursion playable from concealment, letting you bypass traditional mana costs by paying life instead—a steep-looking price easily offset by the steady stream of life gained through Proper Burial whenever a creature perishes. Finally, Bile Urchin acts as both the sacrificial engine and the win condition, bleeding your opponents dry one life at a time through its repeatable activation.
