Leonardo, Sewer Samurai + Tatterkite + Krark-Clan Ironworks + Armor Wars

Leonardo, Sewer Samurai

Tatterkite

Krark-Clan Ironworks

Armor Wars

How it works

1. Cast Tatterkite from your graveyard by paying 2 due to Armor Wars. It won't enter with a finality counter on it due to its static ability.
2. Activate Krark-Clan Ironworks by sacrificing Tatterkite, adding CC
3. Repeat.

This recursive loop relies on the synergy between Leonardo, Sewer Samurai and Armor Wars to repeatedly pull Tatterkite out of your graveyard for a cheap mana investment. Because Tatterkite's static ability prevents it from receiving any counters, it completely bypasses the finality counter restriction that Leonardo, Sewer Samurai would normally impose upon casting it from the graveyard. Once Tatterkite hits the battlefield, you simply feed it to Krark-Clan Ironworks to generate more colorless mana than you spent casting it, fueling an endless cycle that yields an infinite storm count and endless sacrifice triggers.
