Mortuary + Carrion Feeder + Relic Vial + Gwenom, Remorseless

Mortuary

Carrion Feeder

Relic Vial

Gwenom, Remorseless

How it works

1. Activate Carrion Feeder by sacrificing it.
2. When Carrion Feeder dies, Mortuary and Relic Vial trigger.
3. Resolve the Mortuary trigger, putting Carrion Feeder from your graveyard onto the top of your library.
4. Resolve the Relic Vial 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 lethal loop transforms a humble insect into an engine of continuous drain by exploiting the precise stack interaction between Mortuary and Relic Vial. Since Carrion Feeder is itself a Cleric, Relic Vial effortlessly turns every sacrifice into an opponent life loss and life gain, offsetting the life paid to Gwenom, Remorseless's alternative casting condition. With Gwenom granting permission to cast creatures straight off the top of your library for life instead of mana, Mortuary ensures Carrion Feeder is perpetually waiting right where you need it to be sacrificed all over again.
