Mortuary + Vizier of the Menagerie + Endless One

Mortuary

Vizier of the Menagerie

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 engine uses Endless One cast for zero mana as a self-sacrificing loop, dying instantly to state-based actions as a 0/0 creature. Mortuary catches the creature as it hits the graveyard and neatly tucks it right back onto the top of your library. Meanwhile, Vizier of the Menagerie provides the crucial static ability that lets you look at and recast that exact creature straight from the top of your library again and again. Because the Vizier also allows you to spend mana of any type to cast your creature spells, you can churn through this cycle endlessly to generate infinite storm count, creature enters-the-battlefield triggers, and deaths.
