Gonti's Aether Heart + Whirler Virtuoso + Bard, King of Dale

Gonti's Aether Heart

Whirler Virtuoso

Bard, King of Dale

How it works

1. Activate Whirler Virtuoso by paying EEE, creating two 1/1 Thopter artifact creature tokens due to Bard.
2. When the tokens enter, Gonti's Aether Heart triggers twice, causing you to get EEEE.
3. Repeat.

This loop harnesses an explosive multiplication of energy and tokens to fuel an infinite chain. By leveraging Bard, King of Dale's replacement effect, every activation of Whirler Virtuoso doubles your artifact creature output to generate two Thopter tokens at once. Each of those entering tokens triggers Gonti's Aether Heart twice, feeding you four energy counters—more than enough to pay the initial activation cost and net a profit of energy along the way.
