Enchantment, 1U (2) As Copy Artifact comes into play, you may choose an artifact in play. If you do, Copy Artifact comes into play as a copy of that artifact. It's still an enchantment.1
Illus. Amy Weber
The artifact to copy is chosen at the time this card enters play. If there is no valid artifact to choose, then this card enters play as a global enchantment that has no effect. [D'Angelo 2001/08/31]
As a copy, Copy Artifact copies all initial characteristics of the targeted artifact. This includes name, abilities, whether or not it is a creature and more. [CompRules 2001/07/23 - 503.2/3]
The copy of the artifact is not still blue. It copies the color of the thing it is copying. [Duelist Magazine #14, Page 26]
The copy is both an artifact and an enchantment, so it is an artifact-enchantment (perhaps even an artifact-creature-enchantment). It can be affected by anything which affects either type of permanent. [D'Angelo 1994/06/01]
