Mortuary + Carrion Feeder + Venerated Stormsinger + Gwenom, Remorseless

Mortuary

Carrion Feeder

Venerated Stormsinger

Gwenom, Remorseless

How it works

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

This loop turns a simple self-sacrifice into an infinite drain-and-gain engine by weaponizing the graveyard-to-library redirection of Mortuary. Every time Carrion Feeder consumes itself, Venerated Stormsinger triggers to drain your opponents while Gwenom, Remorseless grants you the crucial top-deck casting permission needed to replay the sacrificed creature. By paying Gwenom's alternative life cost instead of mana, you bypass traditional resource restrictions entirely, using the life cushioned by Venerated Stormsinger to fuel the loop indefinitely.
