When this card attacks, its original ATK is halved until the end of the Damage Step. During battle between this attacking card and a Defense Position monster whose DEF is lower than the ATK of this card, inflict the difference as Battle Damage to your opponent. Once per turn, you can select 1 monster you control, except a Machine-Type monster, and equip it to this card. While equipped by this effect, this card can attack all monsters your opponent controls once each."
