Mite Overseer + Krark-Clan Ironworks + Angelic Chorus + Stridehangar Automaton

Mite Overseer

Krark-Clan Ironworks

Angelic Chorus

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, Angelic Chorus 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 elegant loop centers on turning Mite Overseer's Phyrexian Mite ability into a self-sustaining engine, wonderfully amplified by Stridehangar Automaton's replacement effect to spit out an extra Thopter alongside every Mite you make. By feeding both newly spawned artifact tokens right into Krark-Clan Ironworks, you generate more than enough colorless mana to continuously fund the Overseer's activation cost while netting a surplus. Meanwhile, the presence of Angelic Chorus turns every incoming creature pair into a steady stream of lifegain, padding your life total enough to easily pay down any Phyrexian mana costs along the way.
