Mite Overseer + Krark-Clan Ironworks + Stridehangar Automaton + Case of the Uneaten Feast

Mite Overseer

Krark-Clan Ironworks

Stridehangar Automaton

Case of the Uneaten Feast

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, Case of the Uneaten Feast 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 engine turns life-payment and token generation into a closed loop, fueled entirely by the conversion rates of Krark-Clan Ironworks. By paying into Mite Overseer's ability, Stridehangar Automaton steps in to double your output, yielding both a Phyrexian Mite and an extra Thopter whenever you activate it. Every time these tokens enter, Case of the Uneaten Feast effortlessly cushions the life payment by triggering on each arrival, ensuring your health stays intact. Finally, sacrificing both new artifacts back to Krark-Clan Ironworks generates more than enough colorless mana to sustain the loop indefinitely while churning out infinite triggers.
