Mortuary + Shifting Wall + High-Society Hunter

Mortuary

Shifting Wall

High-Society Hunter

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 High-Society Hunter.
3. Resolve the Mortuary trigger, putting Shifting Wall from your graveyard onto the top of your library.
4. Resolve the High-Society Hunter trigger, causing you to draw a card, thus drawing Shifting Wall from your library.
5. Repeat.

This clever loop turns the zero-mana cost of Shifting Wall into an infinite mechanical engine by exploiting its zero-toughness nature. As soon as Shifting Wall enters the battlefield, state-based actions send it straight to the graveyard, triggering Mortuary to seamlessly recycle the creature right back to the top of your library. Meanwhile, High-Society Hunter watches this endless cycle of demise, capitalizing on the creature's death to draw you a card and effortlessly put Shifting Wall back into your hand for another iteration.
