Mortuary + Bolas's Citadel + Tinder Wall + Funeral Room // Awakening Hall

Mortuary

Bolas's Citadel

Tinder Wall

Funeral Room // Awakening Hall

How it works

1. Activate Tinder Wall by sacrificing it.
2. When Tinder Wall dies, Mortuary and Funeral Room // Awakening Hall trigger.
3. Resolve the Mortuary trigger, putting Tinder Wall from your graveyard onto the top of your library.
4. Resolve the Funeral Room // Awakening Hall trigger, causing you to gain 1 life and each opponent to lose 1 life.
5. Cast Tinder Wall from the top of your library by paying 1 life.
6. Repeat.

This clever loop lets you turn life into a self-sustaining engine by turning Bolas's Citadel into a way to cast spells straight from the top of your library using life instead of mana. As you sacrifice Tinder Wall for red mana, Mortuary catches it on the way to the graveyard and dutifully tucks it right back onto the top of your library, ready to be recast. Meanwhile, Funeral Room // Awakening Hall acts as your win condition and life stabilizer, draining your opponents and healing you every single time the wall dies.
