Mortuary + Bolas's Citadel + Carrion Feeder + Rograkh, Son of Rohgahh

Mortuary

Bolas's Citadel

Carrion Feeder

Rograkh, Son of Rohgahh

How it works

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

This clever loop relies on the zero-mana cost of Rograkh, Son of Rohgahh to turn Carrion Feeder into an engine for infinite sacrifices, creature triggers, and storm count. Whenever you sacrifice Rograkh to feed Carrion Feeder's appetite, Mortuary instantly redirects the legendary kobold from your graveyard right back to the top of your library. From there, Bolas's Citadel allows you to recast Rograkh for zero life over and over again, fueling an unending cycle of death and rebirth.
