Automated Assembly Line + Gonti's Aether Heart + Demon of Dark Schemes + Viscera Seer

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Viscera Seer

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 Viscera Seer by sacrificing the Robot.
4. When the Robot dies, Demon of Dark Schemes' second ability triggers, causing you to get E.
5. Resolve the Viscera Seer ability, causing you to scry 1.
6. Repeat.

This clever engine turns energy and artifacts into a self-sustaining loop of creation and sacrifice, fueled entirely by Automated Assembly Line's ability to forge a 3/3 Robot token for three energy. As that token enters, Gonti's Aether Heart steps in to pad your energy reserves with two more counters, completely offsetting the conversion cost when paired with the single energy you reap from Demon of Dark Schemes whenever a creature perishes. You simply feed the newly minted Robot to Viscera Seer to instantly trigger that death bonus while digging through your library with endless scry 1 triggers, leaving you with infinite sacrifices, enters-the-battlefield events, and leaves-the-battlefield triggers.
