Automated Assembly Line + Gonti's Aether Heart + Demon of Dark Schemes + Carrion Feeder

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Carrion Feeder

How it works

1. Activate Automated Assembly Line by paying EEE, creating a 3/3 Robot artifact creature token.
2. When the Robot enters the battlefield, Gonti's Aether Heart triggers, causing you to get EE.
3. Activate Carrion Feeder by sacrificing the Robot.
4. When the Robot dies, Demon of Dark Schemes' second ability triggers, causing you to get E.
5. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
6. Repeat.

This ingenious engine harnesses the synergy of energy generation and sacrifice to fuel an endless loop of creation and destruction. By using Automated Assembly Line to manufacture Robot tokens that trigger Gonti's Aether Heart upon entering the battlefield, you accumulate the necessary energy to continuously pay the Assembly Line's activation cost. Meanwhile, Carrion Feeder acts as the designated outlet to sacrifice those tokens, which in turn causes Demon of Dark Schemes to generate even more energy whenever a creature dies.
