Mortuary + Fleshtaker + Bolas's Citadel + Tinder Wall

Mortuary

Fleshtaker

Bolas's Citadel

Tinder Wall

How it works

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

This ingenious loop turns a modest wall into an engine of endless power, centered around Mortuary to instantly recycle any fallen creature back to the top of your library. Bolas's Citadel breaks open the top of your library so you can continuously cast Tinder Wall right back out into play for a mere drop of life rather than its actual mana cost. Meanwhile, Fleshtaker acts as the administrative heart of the operation, giving you a safe place to sacrifice the creature while padding your life total and smoothing your draws with its scry ability. The best part? Tinder Wall's own sacrifice ability generates the red mana you need to fuel Fleshtaker's pump activation, ensuring the whole operation sustains itself indefinitely while netting you an unstoppable storm count and limitless triggers.
