You 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.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
