Leonardo, Sewer Samurai + Tatterkite + Urza, Lord Protector + Krark-Clan Ironworks

Leonardo, Sewer Samurai

Tatterkite

Urza, Lord Protector

Krark-Clan Ironworks

How it works

1. Cast Tatterkite from your graveyard by paying 2 due to Urza. 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 clever loop relies on Leonardo, Sewer Samurai to repeatedly pull Tatterkite out of your graveyard, utilizing Urza, Lord Protector to reduce the casting cost so you can churn through spells with ease. As Tatterkite enters the battlefield, its own static ability cleverly overrides the finality counter that Leonardo would normally impose, keeping the mechanical cycle pristine and uninterrupted. Finally, Krark-Clan Ironworks feeds on this endless supply of creatures by turning each sacrifice into raw colorless mana, fueling your engine to generate infinite artifact and creature triggers alongside a massive storm count.
