Mortuary + Viscera Seer + Crimson Kobolds + Bolas's Citadel

Mortuary

Viscera Seer

Crimson Kobolds

Bolas's Citadel

How it works

1. Activate Viscera Seer by sacrificing Crimson Kobolds
2. When Crimson Kobolds dies, Mortuary triggers, putting Crimson Kobolds from your graveyard onto the top of your library.
3. Resolve the Viscera Seer ability.
4. Cast Crimson Kobolds from the top of your library by paying 0 life.
5. Repeat.

This clever loop lets you endlessly sacrifice and recast zero-mana creatures right from the top of your library. By utilizing Viscera Seer to feed Crimson Kobolds to the graveyard, Mortuary ensures the little kobold immediately goes back onto your library instead of staying lost. Meanwhile, Bolas's Citadel is the true engine that holds the whole operation together, allowing you to bypass mana costs entirely and cast Crimson Kobolds straight off the top for zero life, feeding an infinite storm count and endless death triggers in the process.
