Leonardo, Sewer Samurai + Solemnity + Thermopod + Rograkh, Son of Rohgahh

Leonardo, Sewer Samurai

Solemnity

Thermopod

Rograkh, Son of Rohgahh

How it works

1. Activate Thermopod 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 sets up an infinite red mana engine by turning Rograkh, Son of Rohgahh into a reusable sacrifice fodder for Thermopod. While Leonardo, Sewer Samurai normally brands creatures cast from your graveyard with a finality counter, Solemnity acts as a crucial anchor by completely preventing counters from being placed on creatures. Without that drawback, you can continuously cast Rograkh for zero mana from the graveyard whenever it hits the bin, sacrifice it to Thermopod for mana, and repeat the process endlessly for infinite triggers and resources.
