Automated Assembly Line + Gonti's Aether Heart + Stridehangar Automaton

Automated Assembly Line

Gonti's Aether Heart

Stridehangar Automaton

How it works

1. Activate Automated Assembly Line by paying EEE, creating a 1/1 Thopter and a 3/3 Robot artifact creature token.
2. When the Robot and Thopter enter the battlefield, Gonti's Aether Heart triggers twice, causing you to get EEEE.
3. Repeat.

This clever energy loop runs on a remarkably self-sustaining engine, powered by the synergy between Automated Assembly Line, Gonti's Aether Heart, and Stridehangar Automaton. When you spend energy to activate Automated Assembly Line, Stridehangar Automaton steps in to turn that single robot creation into both a 3/3 Robot and an extra 1/1 Thopter artifact creature token. Because Gonti's Aether Heart triggers twice whenever any artifact enters the battlefield under your control, those arriving tokens generously refill your energy reserves with four new counters—leaving you with a net profit of energy after paying the assembly line's activation cost. This surplus lets you loop the process indefinitely, flooding the board with an endless army of artifacts while generating boundless energy for whatever else your strategy requires.
