One ruling from Wizards of the Coast
- 15 April 2013You may activate this card’s equip ability targeting the creature that it is currently attached to, even if it’s the only creature you control. Since the equip ability costs zero, you can do this as many times as you like during your main phases, though it generally won’t do anything.
