Mortuary + Experimental Frenzy + Priest of Urabrask + Ashnod's Altar

Mortuary

Experimental Frenzy

Priest of Urabrask

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Priest of Urabrask, adding CC.
2. When Priest of Urabrask dies, Mortuary triggers, putting Priest of Urabrask on top of your library from your graveyard.
3. Cast Priest of Urabrask from the top of your library by paying 2.
4. When Priest of Urabrask enters the battlefield, it triggers, adding .
5. Repeat.

This clever loop turns the top of your library into an endless armory, fueled entirely by a self-sustaining cycle of sacrifice and rebirth. Ashnod's Altar provides the colorless mana to recast your threats while sending them straight to the graveyard, where Mortuary immediately intercepts Priest of Urabrask to place it right back on top of your library. Meanwhile, Experimental Frenzy bypasses normal hand restrictions to let you cast that exact same Priest of Urabrask directly from the library, which in turn nets a profit of red mana every time it enters the battlefield thanks to its own trigger.
