Mortuary + Thermopod + Rograkh, Son of Rohgahh + Gwenom, Remorseless

Mortuary

Thermopod

Rograkh, Son of Rohgahh

Gwenom, Remorseless

How it works

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

This loop relies on the zero-mana cost of Rograkh, Son of Rohgahh to create a completely self-sustaining engine. You begin by sacrificing Rograkh to Thermopod, generating red mana and sending the commander to the graveyard, where Mortuary immediately intercepts it to place it right back on top of your library. From there, Gwenom, Remorseless steps in to let you cast spells off the top of your library—and since Rograkh has a mana value of zero, Gwenom allows you to recast it for zero life. Repeating this sequence yields infinite red mana along with infinite death, sacrifice, and entry triggers.
