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

Mortuary

Viscera Seer

Bolas's Citadel

Crookshank Kobolds

How it works

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

This elegant loop turns the zero-cost Crookshank Kobolds into a relentless engine of sacrifice, feeding Viscera Seer over and over while Mortuary dutifully recycles the creature straight back to the top of your library. Because Bolas's Citadel allows you to cast spells directly from the top of your library by paying life instead of mana, and the Kobolds cost zero mana to cast, you can repeat this cycle infinitely without ever running out of resources. The result is a surging storm count and endless death triggers, all orchestrated without spending a single drop of mana.
