Mortuary + Endless One + Weatherlight Compleated

Mortuary

Endless One

Weatherlight Compleated

How it works

1. Cast Endless One by paying 0.
2. Endless One enters and dies as a state-based action due to having 0 toughness, triggering Mortuary and Weatherlight Compleated.
3. Resolve the Mortuary trigger, putting Endless One from your graveyard onto the top of your library.
4. Resolve the Weatherlight Compleated trigger, causing you to put a phyresis counter on it and draw a card, thus drawing Omarthis from your library.
5. Repeat.

This clever loop relies on casting Endless One for zero mana, allowing state-based actions to send it straight to the graveyard the moment it enters the battlefield. Mortuary swoops in to intercept it there, neatly recycling the creature back to the top of your library so you can draw it again. Meanwhile, Weatherlight Compleated watches the carnage unfold, rewarding every single death by ticking up its phyresis counters and fueling your card draw so you can spin through your deck indefinitely.
