Mortuary + Thermopod + Ornithopter + Gwenom, Remorseless

Mortuary

Thermopod

Ornithopter

Gwenom, Remorseless

How it works

1. Activate Thermopod by sacrificing Ornithopter
2. When Ornithopter dies, Mortuary triggers, putting Ornithopter from your graveyard onto the top of your library.
3. Cast Ornithopter from the top of your library by paying 0 life.
4. Repeat.

This loop turns a humble free sacrifice outlet and a zero-mana artifact into a self-sustaining engine. With Thermopod converting each sacrificed creature into red mana, Mortuary ensures that any creature sent to the graveyard simply returns right to the top of your library. From there, Gwenom, Remorseless grants you the ability to cast cards straight off the top of your library for free—paying life instead of mana costs, which conveniently costs zero life for Ornithopter. You can endlessly loop the tiny flyer to generate infinite death triggers, sacrifice triggers, and red mana to fuel the rest of your game plan.
