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

Automated Assembly Line

Gonti's Aether Heart

Demon of Dark Schemes

Atog

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 Atog by sacrificing the Robot.
4. When the Robot dies, Demon of Dark Schemes' second ability triggers, causing you to get E.
5. Resolve the Atog ability, giving it +2/+2 until end of turn.
6. Repeat.

This clever loop is fueled by Automated Assembly Line, which lets you spend energy to manufacture Robot artifact creature tokens on demand. Each time one of those Robots enters the battlefield, Gonti's Aether Heart kicks in to supply a fresh influx of energy, while Demon of Dark Schemes watches the graveyard and rewards you with even more energy whenever a creature perishes. You can then feed those very same tokens to Atog, sacrificing the Robots to pump its power to astronomical heights. Because the energy generated by the entry and subsequent death of each Robot covers the cost to spin up another, the whole assembly line runs in an endless, self-sustaining cycle of creation and destruction.
