Mortuary + Garruk's Horde + Endless One

Mortuary

Garruk's Horde

Endless One

How it works

1. Cast Endless One either from your hand or from the top of your library by paying 0.
2. Endless One enters the battlefield and dies as a state-based action due to having zero toughness.
3. Mortuary triggers, putting Endless One on top of your library from your graveyard.
4. Repeat.

This clever loop turns a single free creature into an endless engine of resurrection and casting. By casting Endless One with an X cost of zero, state-based actions immediately send it to the graveyard, which triggers Mortuary to place it right back on top of your library. From there, Garruk's Horde steps in as the linchpin of the combo, letting you peer into the future and continuously recast Endless One directly from the top of your library without ever needing to draw it.
