Mortuary + Fleshtaker + Mogg Fanatic + Gwenom, Remorseless

Mortuary

Fleshtaker

Mogg Fanatic

Gwenom, Remorseless

How it works

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

This loop creates an infinite self-sustaining cycle of sacrifice by turning Mogg Fanatic into a reusable projectile. When you sacrifice Mogg Fanatic to its own ability, Mortuary immediately intercepts it from the graveyard to place it right back on top of your library. Meanwhile, Fleshtaker provides a convenient sacrifice outlet that rewards you with lifegain and scry triggers whenever another creature bites the dust. Gwenom, Remorseless ties the whole engine together by letting you bypass conventional mana costs entirely, allowing you to replay Mogg Fanatic straight from the top of your library by simply paying life instead.
