Mortuary + Moldervine Reclamation + Marketback Walker

Mortuary

Moldervine Reclamation

Marketback Walker

How it works

1. Cast Marketback Walker by paying 0.
2. Marketback Walker enters and dies as a state-based action due to having 0 toughness, triggering Mortuary and Moldervine Reclamation.
3. Resolve the Mortuary trigger, putting Marketback Walker from your graveyard onto the top of your library.
4. Resolve the Moldervine Reclamation trigger, causing you to draw a card, thus drawing Marketback Walker from your library, and gain 1 life.
5. Repeat.

This ingenious loop turns a zero-cost creature into a self-sustaining engine by exploiting the interaction between the graveyard and your library. When you cast Marketback Walker for zero mana, its lack of toughness causes it to instantly perish as a state-based action, which simultaneously awakens both Mortuary to intercept the creature and place it neatly back onto your library and Moldervine Reclamation to reward you with a life and a drawn card. Because Marketback Walker is placed precisely where Moldervine Reclamation draws from, you draw it right back into your hand to recast it, creating an unbreakable cycle of life, cards, and triggers.
