Leonardo, Sewer Samurai

Tatterkite

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Krark-Clan Ironworks

How it works

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

This clever loop transforms Tatterkite into a self-sustaining sacrifice engine thanks to a clever rules interaction: Tatterkite's static ability prevents counters from being put on it, completely bypassing the finality counter that Leonardo, Sewer Samurai would normally impose when casting it from the graveyard. This allows you to repeatedly cast Tatterkite for just two mana, fueling Krark-Clan Ironworks to generate a surplus of colorless mana. Meanwhile, every single casting triggers Birgi, God of Storytelling to refund red mana and fuel your storm count, letting you churn through your graveyard indefinitely.
