This clever loop transforms The Eternity Elevator into a creature using Rise and Shine, letting it tap for three colorless mana instead of relying on its later station ability. We then channel two of that mana into Voltaic Construct to untap the elevator, leaving a net profit of one mana each cycle. Because Voltaic Construct's untap ability targets *any* artifact creature, it seamlessly resets our newly animated power source, allowing us to generate infinite untaps and infinite colorless mana that we can ultimately funnel back into the elevator's massive mana-producing activation for an infinite supply of any colored mana we desire.
