Mortuary + Falkenrath Noble + Mogg Fanatic + Bolas's Citadel

Mortuary

Falkenrath Noble

Mogg Fanatic

Bolas's Citadel

How it works

1. Activate Mogg Fanatic by sacrificing it.
2. When Mogg Fanatic dies, Mortuary and Falkenrath Noble trigger.
3. Resolve the Mortuary trigger, putting Mogg Fanatic from your graveyard onto the top of your library.
4. Resolve the Falkenrath Noble 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 cunning loop turns a humble goblin into an engine of relentless doom by routing it endlessly through the library. When you activate Mogg Fanatic to fling damage at a target, its demise triggers Mortuary to seamlessly recycle it right back to the top of your library. From there, Bolas's Citadel steps in as the ultimate enabler, letting you bypass traditional mana costs to recast the goblin from the top of your library simply by paying 1 life instead. Meanwhile, Falkenrath Noble watches the carnage unfold, draining your opponents and padding your life total with every single iteration to comfortably offset the Citadel's life-payment cost.
