Automated Assembly Line + Gonti's Aether Heart + Demon of Dark Schemes + Arcbound Ravager

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Arcbound Ravager

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 Arcbound Ravager by sacrificing the Robot.
4. When the Robot dies, Demon of Dark Schemes' second ability triggers, causing you to get E.
5. Resolve the Arcbound Ravager ability, putting a +1/+1 counter on it.
6. Repeat.

This energetic feedback loop turns the rapid construction and destruction of metal into an unstoppable powerhouse. By spending energy through Automated Assembly Line to create a Robot artifact creature token, you immediately trigger Gonti's Aether Heart to restock your energy reserves with every entry. Sacrificing that token to Arcbound Ravager not only pumps its stats using modular, but also counts as a creature dying to fuel Demon of Dark Schemes' energy generation. Because the energy generated across these triggers sustains the assembly line's activation cost, you can cycle the token endlessly to grow an infinitely massive Arcbound Ravager while generating infinite enter-the-battlefield, death, and sacrifice triggers.
