Dragon Noirdencre DR1-FR063

Once per turn, during your Main Phase, if you control this card on the Field, you can equip this card to your "Darkblade" as an Equip Magic Card, OR release this Union equipment and Special Summon this card in Attack Position. Only while this card is equipped by the effect of this card, increase the ATK and DEF of that monster by 400 points, and when it attacks a monster in Defense Position with an ATK higher than the DEF of that monster, inflict the difference as Battle Damage to your opponent's Life Points. (A monster can only be equipped with 1 Union monster at a time. If the monster this card is equipped to is destroyed as a result of battle, destroy this card instead.)
