Card Rulings:Double Attack


 * Discarding a monster for "Double Attack" is a cost.


 * This effect targets.


 * If you use "Cost Down" so that your "Blue-Eyes White Dragon" in your hand is Level 6, then you cannot discard it to activate "Double Attack" and target your Level 7 "Dark Magician" on the field.


 * If you use "Double Attack" on a monster such as "Twinheaded Beast" it still only gets two attacks, not three.


 * You cannot discard a Level 1 monster for "Double Attack".
