Except during the Damage Step (Quick Effect): You can target 1 Warrior Fusion Monster you control; equip this card from your field or GY to that monster you control as an Equip Spell. You can only use this effect of "Fighting Flame Dragon" once per turn. While this card is equipped to "Flame Swordsman" or a monster that mentions it, the equipped monster gains 700 ATK and can make a second attack during each Battle Phase.
