Mortuary + Overgrowth Elemental + Tinder Wall + Gwenom, Remorseless

Mortuary

Overgrowth Elemental

Tinder Wall

Gwenom, Remorseless

How it works

1. Activate Tinder Wall by sacrificing it.
2. When Tinder Wall dies, Mortuary and Overgrowth Elemental trigger.
3. Resolve the Mortuary trigger, putting Tinder Wall from your graveyard onto the top of your library.
4. Resolve the Overgrowth Elemental trigger, 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 a simple wall into a self-sustaining mana and life engine by manipulating the top of your library. When you sacrifice Tinder Wall for red mana, its death triggers Mortuary to tuck it safely back onto your library while Overgrowth Elemental gains a +1/+1 counter and pads your life total. Meanwhile, Gwenom, Remorseless is the key enabler letting you bypass standard resource constraints by casting Tinder Wall directly from the top of your library for a sliver of life instead of mana.
