Mortuary + Liliana, Dreadhorde General + Hangarback Walker

Mortuary

Liliana, Dreadhorde General

Hangarback Walker

How it works

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

This clever engine centers around casting Hangarback Walker for zero mana, allowing state-based actions to immediately send it to the graveyard. The presence of Mortuary ensures that your fallen automaton never stays in the graveyard, seamlessly recycling it directly onto the top of your library instead. From there, Liliana, Dreadhorde General converts every single one of those deaths into a guaranteed card draw, putting Hangarback Walker right back into your hand to repeat the entire cycle.
