Mortuary + Vindictive Vampire + Bolas's Citadel + Tinder Wall

Mortuary

Vindictive Vampire

Bolas's Citadel

Tinder Wall

How it works

1. Activate Tinder Wall by sacrificing it.
2. When Tinder Wall dies, Mortuary and Vindictive Vampire trigger.
3. Resolve the Mortuary trigger, putting Tinder Wall from your graveyard onto the top of your library.
4. Resolve the Vindictive Vampire trigger, causing you to gain 1 life and dealing 1 damage to each opponent.
5. Cast Tinder Wall from the top of your library by paying 1 life.
6. Repeat.

This clever loop leverages Bolas's Citadel to bypass traditional mana costs altogether, allowing you to repeatedly cast Tinder Wall straight from the top of your library simply by paying its mana value in life. Whenever Tinder Wall is sacrificed for red mana, Mortuary catches it on its way to the graveyard and instantly recycles it back to the top of your library. Meanwhile, Vindictive Vampire sits ready to capitalize on this endless cycle, draining your opponents' life totals and padding your own life total to fuel the Citadel's life-payment requirement.
