Leonardo, Sewer Samurai + Solemnity + Woe Strider + Rograkh, Son of Rohgahh

Leonardo, Sewer Samurai

Solemnity

Woe Strider

Rograkh, Son of Rohgahh

How it works

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

This clever loop relies on Leonardo, Sewer Samurai to repeatedly cast Rograkh, Son of Rohgahh straight from your graveyard thanks to Rograkh's low power and toughness, while Solemnity politely steps in to prevent the finality counters that would normally exile him. Meanwhile, Woe Strider serves as the ultimate sacrifice outlet to send Rograkh back to the graveyard while granting you infinite scry triggers and death fodder. The Goat token created by Woe Strider when it enters helps bootstrap the process, and the entire engine loops endlessly at zero mana for Rograkh to generate unbounded sacrifice triggers and storm count.
