Leonardo, Sewer Samurai + Solemnity + Umbral Collar Zealot + Memnite

Leonardo, Sewer Samurai

Solemnity

Umbral Collar Zealot

Memnite

How it works

1. Activate Umbral Collar Zealot by sacrificing Memnite.
2. Cast Memnite from your graveyard by paying 0. It will not enter with a finality counter on it due to Solemnity.
3. Repeat.

This ingenious loop relies on Solemnity to completely blank the finality counter drawback on Leonardo, Sewer Samurai, allowing you to recast Memnite from your graveyard over and over for free. Each time you loop, Umbral Collar Zealot provides the necessary sacrifice outlet to send Memnite right back to the graveyard while letting you surveil through your entire deck. Because Memnite costs zero mana to cast, this continuous cycle generates an infinite storm count alongside limitless creature enters-the-battlefield, leaves-the-battlefield, and death triggers.
