This clever engine transforms your entire creature base into metal and mana through a synergistic loop. With The Flesh Is Weak on the battlefield, its passive ability turns any creature bearing a +1/+1 counter—including Rainveil Rejuvenator itself—into an artifact in addition to its other types. This type change is the secret to everything, allowing Rainveil Rejuvenator to qualify as a target for Voltaic Construct's untap ability. You simply tap Rainveil Rejuvenator for its green mana, then pay a portion of that mana into Voltaic Construct to untap it, looping the process to generate infinite green mana.
