Mortuary + Vindictive Vampire + Tinder Wall + Gwenom, Remorseless

Mortuary

Vindictive Vampire

Tinder Wall

Gwenom, Remorseless

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, dealing 1 damage to each opponent and causing you to gain 1 life.
5. Cast Tinder Wall from the top of your library by paying 1 life.
6. Repeat.

This loop turns Gwenom, Remorseless into an engine of pure recycling by letting you cast creatures straight off the top of your library for a mere sliver of life instead of their usual mana cost. When you sacrifice Tinder Wall for its red mana, Mortuary catches it on the way to the graveyard and instantly stacks it back on top of your library for the next iteration. Meanwhile, Vindictive Vampire quietly watches the carnage unfold, turning every single sacrifice loop into a relentless drain of life that closes out the game while your mana pool overflows.
