Mortuary + Carmen, Cruel Skymarcher + Tinder Wall + Gwenom, Remorseless

Mortuary

Carmen, Cruel Skymarcher

Tinder Wall

Gwenom, Remorseless

How it works

1. Activate Tinder Wall by sacrificing it.
2. When Tinder Wall dies, Mortuary and Carmen trigger.
3. Resolve the Mortuary trigger, putting Tinder Wall from your graveyard onto the top of your library.
4. Resolve the Carmen trigger, causing you to gain 1 life and put a +1/+1 counter on Carmen.
5. Cast Tinder Wall from the top of your library by paying 1 life.
6. Repeat.

This ingenious loop turns Tinder Wall into a self-sustaining engine by leveraging Mortuary to constantly recycle it back to the top of your library every time it's sacrificed for red mana. Meanwhile, Carmen, Cruel Skymarcher acts as the growth-and-trigger hub, accumulating endless +1/+1 counters and life from the sacrifices while raising her power to effortlessly accommodate other recursion loops. This sets up Gwenom, Remorseless to safely take over the casting duties from the top of your library, paying life instead of mana to keep the sequence rolling infinitely.
