Mortuary + Shilgengar, Sire of Famine + Fear of Lost Teeth + Gwenom, Remorseless

Mortuary

Shilgengar, Sire of Famine

Fear of Lost Teeth

Gwenom, Remorseless

How it works

1. Activate Shilgengar by sacrificing Fear of Lost Teeth.
2. When Fear of Lost Teeth dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Fear of Lost Teeth from your graveyard onto the top of your library.
4. Resolve the Fear of Lost Teeth trigger, causing you to gain 1 life and dealing 1 damage to any target
5. Resolve the Shilgengar ability.
6. Cast Fear of Lost Teeth from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This looping loop turns sacrifice into a self-sustaining engine by orchestrating how cards cycle through your zones. Shilgengar, Sire of Famine provides the outlet to sacrifice Fear of Lost Teeth, which naturally triggers its own death ability while simultaneously feeding Mortuary to instantly recycle it straight back to the top of your library. From there, Gwenom, Remorseless steps in to let you play that creature directly from the top of your library, bypassing mana costs by paying life instead—a cost easily offset by the life gained from the dying Fear of Lost Teeth.
