Mortuary + Moldervine Reclamation + Shifting Wall

Mortuary

Moldervine Reclamation

Shifting Wall

How it works

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

By casting Shifting Wall for zero mana, we exploit the creature's zero-toughness nature to instantly send it to the graveyard as a state-based action the moment it enters the battlefield. This tragic little demise immediately triggers Mortuary, which whisks Shifting Wall right back to the top of our library instead of letting it rest. Simultaneously, Moldervine Reclamation rewards that very same death by padding our life total and drawing us a card, which conveniently puts Shifting Wall right back into our hand to cast all over again.
