Decoction Module + Lae'zel, Vlaakith's Champion + Automated Assembly Line + Yarok, the Desecrated

Decoction Module

Lae'zel, Vlaakith's Champion

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 brilliant engine transforms the simple act of robot manufacturing into a self-sustaining feedback loop, fueled by the multiplicative power of Lae'zel, Vlaakith's Champion. When Automated Assembly Line produces its 3/3 token, Yarok, the Desecrated doubles the resulting entry trigger for Decoction Module. Meanwhile, Lae'zel ensures you gain an extra energy counter every single time Decoction Module triggers, converting what would be a net loss into an absolute surplus. With this surplus of energy, you can infinitely cycle the process to generate boundless entry triggers, tapped artifact creatures, and an endless reservoir of energy.
