Leonardo, Sewer Samurai + Solemnity + Shilgengar, Sire of Famine + Rograkh, Son of Rohgahh

Leonardo, Sewer Samurai

Solemnity

Shilgengar, Sire of Famine

Rograkh, Son of Rohgahh

How it works

1. Activate Shilgengar 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 brilliant loop revolves around Shilgengar, Sire of Famine turning the free-casting Rograkh, Son of Rohgahh into an engine for endless sacrifice and death triggers. Because Rograkh costs zero mana, Leonardo, Sewer Samurai easily pulls him right back out of the graveyard during your turn, bypassing the usual restriction of finality counters entirely thanks to Solemnity shutting down all counter placement. Every iteration lets Shilgengar snack on Rograkh to churn out a fresh Blood token, allowing you to feed the engine indefinitely while generating boundless artifacts and enter-the-battlefield triggers.
