Mortuary + Viscera Seer + Bolas's Citadel + Fear of Lost Teeth

Mortuary

Viscera Seer

Bolas's Citadel

Fear of Lost Teeth

How it works

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

This looping execution turns a humble common into a lethal weapon by bending the rules of where your cards can go. With Mortuary intercepting your creatures as they hit the graveyard and neatly placing them right back on top of your library, you ensure a never-ending supply of fodder for Viscera Seer to sacrifice. Meanwhile, Bolas's Citadel sidesteps traditional mana constraints by letting you recast the threat directly from the top of your library simply by paying life. Fear of Lost Teeth acts as the perfect engine for this machinery, draining your opponents and recovering your life total every single iteration so you can keep paying the Citadel's cost until the table falls.
