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

Mite Overseer

Ashnod's Altar

Anointer 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, Anointer 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 is a brilliant mechanical engine centered around Mite Overseer, whose activated ability uses Phyrexian mana to churn out artifact creature tokens. Stridehangar Automaton serves as a powerful passive multiplier here, ensuring that every time those tokens are generated, an extra Thopter tag-along is created alongside them. Meanwhile, Anointer Priest converts this swelling token parade into a steady stream of life, and Ashnod's Altar seamlessly recycles the entire board into a surplus of colorless mana to fund the next iteration indefinitely.
