Mortuary + Vivien, Monsters' Advocate + Endless One

Mortuary

Vivien, Monsters' Advocate

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 loop relies on the zero-mana casting cost of Endless One, which enters the battlefield with zero toughness and immediately heads to the graveyard as a state-based action. Mortuary catches it on the way down, seamlessly redirecting the creature straight to the top of your library instead of letting it rest. Meanwhile, Vivien, Monsters' Advocate lets you peer at that top card at any time and grants you permission to cast creature spells right off the top of your library. By continuously re-casting the same Endless One for free, you rack up infinite death, entrance, and leave-the-battlefield triggers along with an endless storm count.
