This clever assembly turns a modest mechanical family into an engine of limitless potential. By casting Hulking Metamorph—ideally via its prototype cost or as a copy effect—you can replicate Palladium Myr so that your board features multiple mana-producers capable of generating substantial colorless energy. Meanwhile, Myr Galvanizer provides both a passive pump to your metallic brood and an active untap ability that resets your mana sources, letting you repeatedly tap and untap your Palladium Myr and duplicated threats. The result is an infinite reservoir of colorless mana and boundless untapping power to fuel whatever follows.
