Leonardo, Sewer Samurai + Solemnity + Rograkh, Son of Rohgahh + Yahenni, Undying Partisan

Leonardo, Sewer Samurai

Solemnity

Rograkh, Son of Rohgahh

Yahenni, Undying Partisan

How it works

1. Activate Yahenni 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 turns the zero-mana cost of Rograkh, Son of Rohgahh into a relentless engine of sacrifice and resurrection. While Leonardo, Sewer Samurai normally brands creatures cast from the graveyard with a finality counter that exiles them upon death, Solemnity acts as an absolute ward that stops all counters from ever being placed on creatures. This protection ensures that Rograkh can return from the graveyard endlessly without ever being exiled. Meanwhile, Yahenni, Undying Partisan happily consumes the retreating Kobold over and over again, harvesting a ceaseless harvest of sacrifices, death triggers, and storm count for your victory.
