Mortuary + Omarthis, Ghostfire Initiate + Bolas's Citadel

Mortuary

Omarthis, Ghostfire Initiate

Bolas's Citadel

How it works

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

This clever loop uses Mortuary to instantly recycle Omarthis, Ghostfire Initiate the moment it enters the battlefield and succumbs to state-based actions with zero toughness. With Bolas's Citadel sitting on your battlefield, you can effortlessly cast Omarthis right off the top of your library for zero life over and over again. Because Bolas's Citadel allows you to play directly from the top of your library and Mortuary places Omarthis right back there upon dying, you generate an endless storm count and infinite triggers without ever spending a single resource.
