Gonti's Aether Heart + Whirler Virtuoso + Exalted Sunborn

Gonti's Aether Heart

Whirler Virtuoso

Exalted Sunborn

How it works

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

This loop is an exquisite energy engine that turns a modest stockpile into an unstoppable swarm. Whirler Virtuoso acts as your primary conversion unit, spending the energy you gather to manufacture Thopter tokens, while Exalted Sunborn doubles every single token creation to ensure you get twice the aerial presence. Meanwhile, Gonti's Aether Heart watches those very same artifact tokens enter the battlefield and floods your reserves with even more energy than the Thopters cost to make. By cycling this creation process back and forth, you net infinite energy and an endless army of fliers, and you can even cash out the Aether Heart's massive energy payout to take infinite extra turns.
