Mortuary + Wild Cantor + Bolas's Citadel + Funeral Room // Awakening Hall

Mortuary

Wild Cantor

Bolas's Citadel

Funeral Room // Awakening Hall

How it works

1. Activate Wild Cantor by sacrificing it.
2. When Wild Cantor dies, Mortuary and Funeral Room // Awakening Hall trigger.
3. Resolve the Mortuary trigger, putting Wild Cantor from your graveyard onto the top of your library.
4. Resolve the Funeral Room // Awakening Hall trigger, causing you to gain 1 life and each opponent to lose 1 life.
5. Cast Wild Cantor from the top of your library by paying 1 life.
6. Repeat.

This loop turns the top of your library into an endless revolving door of sacrifice and rebirth, fueled entirely by life rather than mana. By using Bolas's Citadel, you can cast Wild Cantor straight from the top of your library, paying its mana value of one life instead of any mana cost. As soon as Wild Cantor is sacrificed for mana, Mortuary catches it on its way to the graveyard and neatly tucks it right back onto the top of your library to repeat the process. Meanwhile, the Awakening Hall half of Funeral Room // Awakening Hall acts as a relentless drain on your opponents, turning every single iteration of this cycle into a guaranteed life swing that easily outpaces the life you pay to cast the creature.
