Mortuary + Mogg Fanatic + Bolas's Citadel + Susurian Voidborn

Mortuary

Mogg Fanatic

Bolas's Citadel

Susurian Voidborn

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 goblin into an endless cycle of self-sacrifice and rebirth, fueled by the terrifying top-deck engine of Bolas's Citadel. Every time you activate Mogg Fanatic to ping a target, Mortuary steps in to intercept the creature from your graveyard and slide it straight back to the top of your library. From there, Bolas's Citadel lets you recast it instantly for a mere single point of life rather than its mana cost. Meanwhile, the presence of Susurian Voidborn turns this endless procession of deaths into a relentless drain on your opponents' life totals while comfortably padding your own life reserve to keep paying the Citadel's toll.
