Mortuary + Bile Urchin + Bolas's Citadel + Funeral Room // Awakening Hall

Mortuary

Bile Urchin

Bolas's Citadel

Funeral Room // Awakening Hall

How it works

1. Activate Bile Urchin by sacrificing it.
2. When Bile Urchin dies, Mortuary and Funeral Room // Awakening Hall trigger.
3. Resolve the Mortuary trigger, putting Bile Urchin 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. Resolve the Bile Urchin ability.
6. Cast Bile Urchin from the top of your library by paying 1 life.
7. Repeat.

This delightfully macabre loop turns a humble Bile Urchin into a relentless engine of doom, fueled entirely by life rather than mana. By unlocking the Awakening Hall half of Funeral Room // Awakening Hall, its death-trigger ability ensures that every sacrifice drains your opponents while immediately offsetting the life cost needed to recast your spells. Meanwhile, Mortuary steps in to intercept the dying Urchin, seamlessly recycling it straight to the top of your library so Bolas's Citadel can let you play it over and over again without ever missing a beat.
