Im looking for cards that are enchanments or artifacts that give my artifacts like isochron scepter the ability to cost 1 less, also the ability to give my artifacts to not have to tap and just pay the mana cost.... Is there such a thing? If so name the cards please and please correct name spelling so i can search the card thank you.
But removing the "tap" in the cost is not possible; the closest thing is untapping the artifact (Voltaic Key, Clock of Omens).
