Mite Overseer + Krark-Clan Ironworks + Leyline of Vitality + Stridehangar Automaton

Mite Overseer

Krark-Clan Ironworks

Leyline of Vitality

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, Leyline of Vitality 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 delightful loop transforms a simple activation into an absolute engine by leveraging token replacement effects and mana recycling. When you activate Mite Overseer, Stridehangar Automaton swoops in to double your production by spitting out both a Phyrexian Mite and an extra Thopter token simultaneously. The arrival of these new artifacts happily greets Leyline of Vitality, padding your life total with every iteration before you feed both tokens right into Krark-Clan Ironworks to generate a surplus of colorless mana. Because the ironworks' sacrifice ability yields more mana than Mite Overseer's activation costs, you are left with an endless cascade of resources, life, and triggers.
