Mortuary + Mogg Fanatic + Bolas's Citadel + Bastion of Remembrance

Mortuary

Mogg Fanatic

Bolas's Citadel

Bastion of Remembrance

How it works

1. Activate Mogg Fanatic by sacrificing it.
2. When Mogg Fanatic dies, Mortuary and Bastion of Remembrance trigger.
3. Resolve the Mortuary trigger, putting Mogg Fanatic from your graveyard onto the top of your library.
4. Resolve the Bastion of Remembrance 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 elegant engine transforms a humble goblin into a repeating source of damage while maintaining a precise loop through your library. When you activate Mogg Fanatic by sacrificing it, both Mortuary and Bastion of Remembrance trigger simultaneously; Mortuary places the creature directly back onto the top of your library, while Bastion of Remembrance drains your opponents and replenishes your life total. Bolas's Citadel then allows you to cast Mogg Fanatic right back off the top of your library, trading a single point of life for the spell's mana cost and letting you repeat the entire process indefinitely.
