Automated Assembly Line + Gonti's Aether Heart + Demon of Dark Schemes + Bartolomé del Presidio

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Bartolomé del Presidio

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

This ingenious engine transforms a simple stream of energy into an endless cycle of creation and sacrifice, using Gonti's Aether Heart to effortlessly fund the three-energy cost to spawn a 3/3 token from Automated Assembly Line every time it enters the battlefield. Once that Robot artifact creature token arrives, you immediately feed it to Bartolomé del Presidio to grow its power with a +1/+1 counter. That death then triggers Demon of Dark Schemes, recouping the final piece of energy needed to keep the loop spinning indefinitely.
