Leonardo, Sewer Samurai + Tatterkite + Krark-Clan Ironworks + Gravebreaker Lamia

Leonardo, Sewer Samurai

Tatterkite

Krark-Clan Ironworks

Gravebreaker Lamia

How it works

1. Cast Tatterkite from your graveyard by paying 2 due to Gravebreaker Lamia. 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 turns the graveyard into an endless engine, fueled by Leonardo, Sewer Samurai's ability to let you recast small creatures from the graveyard during your turn. Gravebreaker Lamia pulls double duty here, not only tutoring up a piece when it enters the battlefield, but also providing a vital cost reduction that makes recurring Tatterkite cheap enough to sustain. Tatterkite's own static ability is the linchpin of the combo, gracefully bypassing Leonardo, Sewer Samurai's drawback by preventing finality counters from ever sticking to it. Finally, Krark-Clan Ironworks harvests the loop by converting the recurring artifact into a net profit of colorless mana, fueling an infinite storm count and endless sacrifice triggers.
