Automated Assembly Line + Gonti's Aether Heart + Demon of Dark Schemes + Goblin Bombardment

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Goblin Bombardment

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 Goblin Bombardment by sacrificing the Robot.
4. When the Robot dies, Demon of Dark Schemes' second ability triggers, causing you to get E.
5. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
6. Repeat.

This loop functions as a clever energy-efficient engine where Gonti's Aether Heart serves as the crucial accumulator, refunding two energy counters every time a new artifact arrives. By funneling that energy alongside the output of Automated Assembly Line, you can repeatedly forge 3/3 Robot artifact creature tokens on demand. Once those tokens are in play, Goblin Bombardment provides the necessary outlet to sacrifice them, which in turn triggers Demon of Dark Schemes to harvest even more energy from the dying creature. The result is a seamless cycle that converts your accumulated resources into endless death triggers and infinite damage.
