Decoction Module

Lae'zel, Vlaakith's Champion

Automated Assembly Line

Virtue of Knowledge // Vantress Visions

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 Automated Assembly Line to churn out 3/3 Robot artifact creature tokens by spending energy, which then immediately fuel the engine. Because Lae'zel, Vlaakith's Champion is present, any energy counters you would get are instead boosted, allowing Decoction Module to generate an excess of energy whenever a Robot enters the battlefield. This surplus is further amplified by Virtue of Knowledge doubling those entry-triggered abilities, ensuring that every token generation easily refunds more than the three energy required to activate Automated Assembly Line again. Meanwhile, Decoction Module's activated ability can even bounce your own creatures if needed, rounding out an endlessly looping factory of metal and energy.
