Mortuary + Grim Haruspex + Marketback Walker

Mortuary

Grim Haruspex

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 Grim Haruspex.
3. Resolve the Mortuary trigger, putting Marketback Walker from your graveyard onto the top of your library.
4. Resolve the Grim Haruspex trigger, causing you to draw a card, thus drawing Marketback Walker from your library.
5. Repeat.

This clever loop turns the zero-toughness nature of Marketback Walker—cast for free with zero counters—into a continuous cycle of life and death. As Marketback Walker enters the battlefield and instantly hits the graveyard as a state-based action, Mortuary steps in to catch it and place it right back on top of your library. Meanwhile, Grim Haruspex keeps watch over the battlefield, triggering off that same death to let you draw a card, which conveniently puts Marketback Walker right back into your hand to be recast.
