Automated Assembly Line + Gonti's Aether Heart + Kaya, Geist Hunter

Automated Assembly Line

Gonti's Aether Heart

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Activate Automated Assembly Line by paying EEE, creating two 3/3 Robot artifact creature tokens.
3. When the Robots enter the battlefield, Gonti's Aether Heart triggers twice, causing you to get EEEE.
4. Repeat.

With Kaya, Geist Hunter's minus ability actively doubling all your token generation for the turn, Automated Assembly Line's token-making ability becomes incredibly efficient, pumping out two 3/3 Robot tokens for just three energy. Because those new artifacts enter the battlefield, Gonti's Aether Heart triggers to replenish your reserves with four energy counters—more than enough to pay for the Assembly Line's activation again and fuel an infinite loop. This generates an unbounded supply of energy, creature tokens, and enters-the-battlefield triggers to overwhelm your opponents.
