Mortuary + Mogg Fanatic + Susurian Voidborn + Gwenom, Remorseless

Mortuary

Mogg Fanatic

Susurian Voidborn

Gwenom, Remorseless

How it works

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

This loop turns a humble sacrifice into a relentless engine of attrition by weaponizing the top of your library. When you activate Mogg Fanatic, its death triggers Susurian Voidborn to drain your opponent's life total while Mortuary quietly catches the goblin and returns it directly to the top of your library. From there, Gwenom, Remorseless steps in to let you cast creatures right off the top, entirely circumventing traditional mana costs by letting you pay life instead—a cost easily offset by the life gained from Susurian Voidborn.
