Leonardo, Sewer Samurai + Solemnity + Carrion Feeder + Shield Sphere

Leonardo, Sewer Samurai

Solemnity

Carrion Feeder

Shield Sphere

How it works

1. Activate Carrion Feeder by sacrificing Shield Sphere.
2. Cast Shield Sphere from your graveyard by paying 0. It will not enter with a finality counter on it due to Solemnity.
3. Repeat.

This elegant loop turns the graveyard into an endless engine, anchored by Leonardo, Sewer Samurai's ability to let you recast low-power creatures right out of your yard. To bypass the downside of those finality counters, Solemnity steps in with its passive ward, ensuring that no counters—neither the finality markers from Leonardo nor the self-inflicted penalties on Shield Sphere—can ever be placed on your permanents. This allows the free zero-mana Shield Sphere to be constantly recast and immediately fed to Carrion Feeder, turning a defensive wall into an infinite cycle of sacrifices that fuels storm count, death triggers, and a growing monstrous Feeder.
