Mortuary + Cruel Celebrant + Carrion Feeder + Gwenom, Remorseless

Mortuary

Cruel Celebrant

Carrion Feeder

Gwenom, Remorseless

How it works

1. Activate Carrion Feeder by sacrificing it.
2. When Carrion Feeder dies, Mortuary and Cruel Celebrant trigger.
3. Resolve the Mortuary trigger, putting Carrion Feeder from your graveyard onto the top of your library.
4. Resolve the Cruel Celebrant 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 clever loop turns your graveyard into an endless supply depot by letting you sacrifice Carrion Feeder to itself repeatedly. Cruel Celebrant ensures that every iteration drains your opponents and pads your life total, while Mortuary quietly intercepts Carrion Feeder as it dies and immediately puts it back on top of your library. From there, Gwenom, Remorseless grants you the vital permission to cast that creature straight from the top of your library, paying life instead of mana to keep the cycle spinning infinitely.
