Mite Overseer + Krark-Clan Ironworks + Hinterland Sanctifier + Stridehangar Automaton

Mite Overseer

Krark-Clan Ironworks

Hinterland Sanctifier

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, Hinterland Sanctifier 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 relies on Stridehangar Automaton to turn a single token activation into a double-token bonanza: every time you pay to create a Phyrexian Mite via Mite Overseer, you get an extra Thopter into the bargain. Those newly minted artifacts immediately feed Krark-Clan Ironworks, which sacrifices them for more than enough colorless mana to fuel the next activation. Meanwhile, Hinterland Sanctifier watches the chaos unfold, converting every single entry into a steady stream of life to keep your engine running.
