Mortuary + Bolas's Citadel + Panicked Bystander // Cackling Culprit + Tinder Wall

Mortuary

Bolas's Citadel

Panicked Bystander // Cackling Culprit

Tinder Wall

How it works

1. Activate Tinder Wall by sacrificing it.
2. When Tinder Wall dies, Mortuary and Panicked Bystander // Cackling Culprit trigger.
3. Resolve the Mortuary trigger, putting Tinder Wall from your graveyard onto the top of your library.
4. Resolve the Panicked Bystander // Cackling Culprit trigger, causing you to gain 1 life
5. Cast Tinder Wall from the top of your library by paying 1 life.
6. Repeat.

This clever loop turns the self-sacrificing mana of Tinder Wall into an endless engine, fueled entirely by life rather than traditional resources. With Bolas's Citadel allowing you to freely play spells directly from the top of your library by paying life instead of mana, you can recast the wall as soon as Mortuary quietly tucks it back on top of your library upon death. Meanwhile, Panicked Bystander // Cackling Culprit sits on the battlefield to continually offset that life-payment with a steady stream of lifegain triggered by each creature's demise, letting you repeat the entire process indefinitely.
