Automated Assembly Line + Gonti's Aether Heart + Demon of Dark Schemes + Shilgengar, Sire of Famine

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Shilgengar, Sire of Famine

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 Shilgengar by sacrificing the Robot.
4. When the Robot dies, Demon of Dark Schemes' second ability triggers, causing you to get E.
5. Resolve the Shilgengar ability
6. Repeat.

This loop is a masterclass in energy resource conversion, turning an initial store of counters into an endless supply of artifact creatures and sacrifices. You begin by spending the energy you've gathered to activate Automated Assembly Line, which drops a 3/3 Robot token onto the battlefield. That new arrival immediately triggers Gonti's Aether Heart to pad your energy reserves, offsetting the cost of production. Next, you feed that freshly minted Robot to Shilgengar, Sire of Famine to generate Blood tokens and feed the machine. When the Robot perishes, Demon of Dark Schemes watches it die to quietly refund your energy, keeping the cycle closed and self-sustaining.
