Text (10+errata): 2/3. ; {Tap}: Gain control of target creature for as long as that creature is enchanted. [Oracle 2009/07/08]
A creature is "enchanted" if it has any Auras on it. [D'Angelo 2007/07/15]
Can target an unenchanted creature but has no effect on that creature. [Aahz 1997/11/17]
The control effect ends if at any time the creature has no enchantments on it. [D'Angelo 1997/12/18]
As long as the target is a creature at the time the ability resolves, the control effect does not end if the target stops being a creature after that. The text "as long as that creature is enchanted" means "as long as the thing that was targeted is enchanted" for purposes of the rules. [D'Angelo 2008/07/12]
