Leonardo, Sewer Samurai + Solemnity + Shilgengar, Sire of Famine + Crimson Kobolds

Leonardo, Sewer Samurai

Solemnity

Shilgengar, Sire of Famine

Crimson Kobolds

How it works

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

This brilliant loop uses Shilgengar, Sire of Famine as the ultimate engine, letting you sacrifice Crimson Kobolds to generate a Blood token thanks to the Kobolds' zero-mana casting cost and tiny stats. Because Solemnity acts as a crucial static shield stopping counters from being placed, it completely nullifies the finality counters that would normally doom the Kobolds—both when Leonardo, Sewer Samurai allows you to recast them straight from the graveyard and when Shilgengar's mass-reanimation ability tries to bring them back. With Leonardo, Sewer Samurai bridging the graveyard to the battlefield, you can endlessly cycle the Crimson Kobolds to churn out infinite sacrifice triggers, death triggers, and Blood tokens.
