Mite Overseer + Ashnod's Altar + Suture Priest + Stridehangar Automaton

Mite Overseer

Ashnod's Altar

Suture Priest

Stridehangar Automaton

How it works

1. Activate Mite Overseer by paying 3W/P, creating two creature tokens.
2. When the creature tokens enter the battlefield, Suture Priest triggers twice, causing you to gain 2 life.
3. Activate Ashnod's Altar twice by sacrificing the creature tokens, adding CCCC.
4. Repeat.

This loop relies on a clever token-generation and mana-filtering engine that turns life into profit. By utilizing Mite Overseer's activated ability, you pay mana or life to drop tokens, which Stridehangar Automaton automatically supercharges by throwing in an extra Thopter whenever artifact tokens are created. Ashnod's Altar then provides the necessary sacrifice outlet to convert those newly minted bodies back into colorless mana, while Suture Priest neatly cushions the life-payment costs by padding your life total every time a creature enters the battlefield.
