Random Card of the Day #154:
Copy Artifact - 1U
You may have Copy Artifact enter the battlefield as a copy of any artifact on the battlefield, except it's an enchantment in addition to its other types.
Classic card. I wonder why they never reprinted it. The closest thing that exist I think is Phyrexian Metamorph.
It even copies Artifact Creatures it's a pretty pro card, even if just to copy your own Blightsteel Colossus.
