Leonardo, Sewer Samurai + Solemnity + Woe Strider + Ornithopter

Leonardo, Sewer Samurai

Solemnity

Woe Strider

Ornithopter

How it works

1. Activate Woe Strider by sacrificing Ornithopter.
2. Cast Ornithopter 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 graveyard into your personal workshop, letting you endlessly recur and sacrifice your artifacts. Woe Strider acts as the engine, providing a reliable sacrifice outlet while letting you sculpt your draws with its scry ability. The real magic happens because Solemnity acts as a blanket prohibition that stops counters from ever being placed on your permanents. This completely bypasses the drawback on Leonardo, Sewer Samurai, allowing you to repeatedly cast Ornithopter from the graveyard for zero mana without ever receiving a finality counter.
