Kiryu DR1-FR064

Once per turn, during your Main Phase, if you control this card on the Field, you can equip this card to your "Darklord" as an Equip Magic Card, OR release this Union Equip 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 900 points, and you can Tribute this card to allow the equipped monster to attack your opponent's Life Points directly this turn. (A monster can only be equipped with 1 Union monster at a time. If the monster that this card is equipped to is destroyed by battle, destroy this card instead.)
