Mortuary + Carmen, Cruel Skymarcher + Mogg Fanatic + Gwenom, Remorseless

Mortuary

Carmen, Cruel Skymarcher

Mogg Fanatic

Gwenom, Remorseless

How it works

1. Activate Mogg Fanatic by sacrificing it.
2. When Mogg Fanatic dies, Mortuary and Carmen trigger.
3. Resolve the Mortuary trigger, putting Mogg Fanatic from your graveyard onto the top of your library.
4. Resolve the Carmen trigger, causing you to gain 1 life and put a +1/+1 counter on Carmen.
5. Resolve the Mogg Fanatic ability.
6. Cast Mogg Fanatic from the top of your library by paying 1 life.
7. Repeat.

This loop transforms a humble sacrifice into an endless cycle of devastation and growth, powered by Mortuary ensuring Mogg Fanatic never truly stays gone by slipping it right back to the top of your library after it hits the graveyard. While Mogg Fanatic handles the damage delivery, Carmen, Cruel Skymarcher watches the sacrifice happen to permanently grow larger with +1/+1 counters and pad your life total, which conveniently helps offset the costs you might incur. Meanwhile, Gwenom, Remorseless provides the critical top-deck advantage that lets you recast Mogg Fanatic directly from the library by paying life instead of mana, keeping the entire engine running indefinitely.
