Ashnod the Uncaring + Bolas's Citadel + Filigree Sages

Ashnod the Uncaring

Bolas's Citadel

Filigree Sages

How it works

1. Activate Bolas's Citadel by tapping it and sacrificing ten other nonland permanents you control.
2. Ashnod the Uncaring triggers, copying Bolas's Citadel's ability.
3. Resolve both Bolas's Citadel abilities, causing each opponent to lose 20 life.
4. Each opponent that had 20 or less life loses the game due to having 0 or less life.
5. Activate Filigree Sages by paying 2, untapping Bolas's Citadel.
6. Activate Bolas's Citadel by tapping it and sacrificing itself, Manifold Key, and eight other nonland permanents you control.
7. Ashnod the Uncaring triggers, copying Bolas's Citadel's ability.
8. Resolve both Bolas's Citadel abilities, causing each opponent to lose 20 life.
9. Each remaining opponent loses the game due to having 0 or less life.

This explosive loop weaponizes the massive sacrifice cost of Bolas's Citadel by turning it into a devastating multi-kill, draining entire tables in a flash. Ashnod the Uncaring serves as the ultimate multiplier, doubling the Citadel's life-drain ability whenever permanents are sacrificed to activate it. Meanwhile, Filigree Sages steps in to untap the Citadel for a modest mana investment, allowing you to repeatedly unleash the copied death-spiral until all of your opponents have lost the game.
