Mortuary + Mogg Fanatic + Zulaport Cutthroat + Bolas's Citadel

Mortuary

Mogg Fanatic

Zulaport Cutthroat

Bolas's Citadel

How it works

1. Activate Mogg Fanatic by sacrificing it.
2. When Mogg Fanatic dies, Mortuary and Zulaport Cutthroat trigger.
3. Resolve the Mortuary trigger, putting Mogg Fanatic from your graveyard onto the top of your library.
4. Resolve the Zulaport Cutthroat trigger, causing you to gain 1 life and each 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 looping engine turns a humble goblin into a lethal win condition by manipulating where your creatures go when they die. By sacrificing Mogg Fanatic to ping a target, you trigger Zulaport Cutthroat to drain your opponents while simultaneously leveraging Mortuary to seamlessly recycle Mogg Fanatic right back onto the top of your library. From there, Bolas's Citadel allows you to bypass mana costs entirely, letting you replay Mogg Fanatic directly from the library by simply paying a single point of life—a cost easily offset by the life gained from Zulaport Cutthroat.
