Decoction Module + Winding Constrictor + Automated Assembly Line + Yarok, the Desecrated

Decoction Module

Winding Constrictor

Automated Assembly Line

Yarok, the Desecrated

How it works

1. Activate Automated Assembly Line by paying EEE, creating a tapped 3/3 Robot artifact creature token.
2. When the Robot enters the battlefield, Decoction Module triggers twice, causing you to get EEEE.
3. Repeat.

This loop relies on turning Automated Assembly Line's energy generation into a self-sustaining engine by exploiting permanent synergy and replacement effects. When Automated Assembly Line spends three energy to create a Robot token, its entry triggers Decoction Module, but Yarok, the Desecrated doubles that entering trigger to generate four energy counters instead of two. Winding Constrictor further supercharges this by adding an extra energy counter to every batch you receive, ensuring you easily outpace the activation cost. With the net surplus of energy, you can infinitely repeat the process to flood the board with tapped creature tokens while amassing infinite energy counters and creature entry triggers.
