Leonardo, Sewer Samurai + Solemnity + Goblin Bombardment + Phyrexian Walker

Leonardo, Sewer Samurai

Solemnity

Goblin Bombardment

Phyrexian Walker

How it works

1. Activate Goblin Bombardment by sacrificing Phyrexian Walker.
2. Cast Phyrexian Walker from your graveyard by paying 0. It will not enter with a finality counter on it due to Solemnity.
3. Repeat.

This delightfully devious loop transforms free artifact creatures into a lethal weapon by bending the rules of the graveyard. Leonardo, Sewer Samurai allows you to endlessly replay tiny threats like Phyrexian Walker right out of your graveyard, completely bypassing their usual restrictions because Solemnity steps in to effortlessly block the finality counters that would otherwise exile them. Once that recycling engine is running smoothly, Goblin Bombardment turns those endless loops into an unstoppable barrage of infinite damage and sacrifice triggers.
