Mortuary + Tinder Wall + Vengeful Bloodwitch + Gwenom, Remorseless

Mortuary

Tinder Wall

Vengeful Bloodwitch

Gwenom, Remorseless

How it works

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

This clever loop uses Mortuary as a recycling engine, ensuring that whenever Tinder Wall hits your graveyard, it instantly returns straight to the top of your library instead of staying put. Gwenom, Remorseless then breaks the rules of normal casting, allowing you to bypass mana costs and recast Tinder Wall directly from the top of your library simply by paying life instead—a cost easily offset by Vengeful Bloodwitch, which drains your opponent's life total and replenishes yours with every single death and sacrifice iteration.
