Mite Overseer + Krark-Clan Ironworks + Prosperous Innkeeper + Stridehangar Automaton

Mite Overseer

Krark-Clan Ironworks

Prosperous Innkeeper

Stridehangar Automaton

How it works

1. Activate Mite Overseer by paying 3W/P, creating a 1/1 Thopter and a 1/1 Phyrexian Mite artifact creature token.
2. When the Phyrexian Mite and Thopter enter, Prosperous Innkeeper triggers twice, causing you to gain 2 life
3. Activate Krark-Clan Ironworks twice by sacrificing the Phyrexian Mite and Thopter, adding CCCC.
4. Repeat.

This loop transforms Mite Overseer's token-creation ability into a self-sustaining engine by leveraging Stridehangar Automaton, which doubles every incoming artifact token into both a Phyrexian Mite and an extra Thopter. Every time these tokens enter the battlefield, Prosperous Innkeeper rewards you with a steady stream of life to cushion the cost of your activations. Finally, you feed those newly minted artifacts straight into Krark-Clan Ironworks, converting them into an abundant surplus of colorless mana to fund the next iteration of the cycle.
