This clever setup uses Mind Transfer Protocol to transform a harmless mana rock into an eligible target for Voltaic Construct, turning the Construct's untap ability into the engine's heartbeat. Once Dreamstone Hedron is granted its new artifact creature status, tapping it yields three colorless mana—more than enough to pay the two mana required by Voltaic Construct to untap it. The result is a self-sustaining loop that generates infinite colorless mana, leaving Dreamstone Hedron primed to be sacrificed for a massive draw of three cards when you finally decide to cash out.
