Unlimited Once per turn during your Main Phase, if you control this monster on the field, you can equip it to your "Freezing Beast" as an Equip Spell-Card OR change it back to a monster in face-up Attack Position. When equipped to a monster by this card?s effect, each time that monster inflicts Battle Damage to your opponent, destroy 1 face-up Spell or Trap Card. (1 monster can only be equipped with 1 Union Monster at a time. If the monster that this card is equipped to is destroyed in battle this card is destroyed instead.)
