Leonardo, Sewer Samurai + Solemnity + Bloodflow Connoisseur + Crookshank Kobolds

Leonardo, Sewer Samurai

Solemnity

Bloodflow Connoisseur

Crookshank Kobolds

How it works

1. Activate Bloodflow Connoisseur by sacrificing Crookshank Kobolds.
2. Cast Crookshank Kobolds from your graveyard by paying 0. It will not enter with a finality counter on it due to Solemnity.
3. Repeat.

This clever loop turns the humble Crookshank Kobolds into an endless sacrifice engine, fueled entirely by the clever synergy between Leonardo, Sewer Samurai and Solemnity. While Leonardo normally saddles creatures cast from your graveyard with a finality counter, Solemnity's strict blanket prohibition completely bypasses that restriction, allowing the zero-mana Kobolds to return time and time again without ever being exiled. As you continuously feed the Kobolds to Bloodflow Connoisseur, you generate infinite sacrifice triggers, death triggers, and a perpetually growing vampire.
