Mortuary + Thermopod + Bolas's Citadel + Fear of Lost Teeth

Mortuary

Thermopod

Bolas's Citadel

Fear of Lost Teeth

How it works

1. Activate Thermopod 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. Cast Fear of Lost Teeth from the top of your library by paying 1 life due to Bolas's Citadel.
6. Repeat.

This loop sets up a self-sustaining engine where Fear of Lost Teeth serves as the perfect fuel for Thermopod, generating red mana while its death simultaneously triggers its own drain ability and Mortuary's placement effect. Because Mortuary immediately tucks Fear of Lost Teeth back onto the top of your library, Bolas's Citadel steps in to let you cast it right back out for life instead of mana. The brilliant synergy here is that casting Fear of Lost Teeth through Bolas's Citadel costs you just 1 life, while its death trigger gives that life right back, neutralizing the Citadel's cost and letting you cycle the loop infinitely for absolute victory.
