Leonardo, Sewer Samurai + Solemnity + Rograkh, Son of Rohgahh + Bloodflow Connoisseur

Leonardo, Sewer Samurai

Solemnity

Rograkh, Son of Rohgahh

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur 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 elegant loop harnesses Leonardo, Sewer Samurai to repeatedly pluck Rograkh, Son of Rohgahh straight from your graveyard for zero mana, fueling an endless stream of sacrifices to Bloodflow Connoisseur to pump it to astronomical sizes. Ordinarily, Leonardo, Sewer Samurai would brandish a finality counter upon that tiny 0/0's return, but Solemnity acts as an absolute metaphysical shield to blank those counters entirely. This allows Rograkh, Son of Rohgahh to hit the graveyard fresh every single time, letting Bloodflow Connoisseur safely convert the infinite loop into boundless sacrifices, death triggers, and storm count.
