Moonbolt, Paragon Blade

Moonbolt, Paragon Blade cannot be equipped to creatures not controlled by its owner. (If the
equipped creature changes controllers to a player other
than the owner, this card is unequipped.)
Whenever equipped creature becomes the target
of a spell or ability an opponent controls, add
mana of any color equal to that spell or ability's converted mana cost to your mana pool.
