Mortuary + Altar of Dementia + Rograkh, Son of Rohgahh + Gwenom, Remorseless

Mortuary

Altar of Dementia

Rograkh, Son of Rohgahh

Gwenom, Remorseless

How it works

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

This elegant loop transforms the ultimate free-to-cast commander, Rograkh, Son of Rohgahh, into an endless sacrifice engine for Altar of Dementia to mill out your opponents. Whenever Rograkh meets his demise, Mortuary steps in to bypass the graveyard entirely, instantly recycling him straight back to the top of your library. From there, Gwenom, Remorseless grants you the crucial ability to play spells directly off your library, allowing you to cast Rograkh repeatedly for zero mana and zero life.
