Forum:Exploder Dragonwing

If exploder dragonwing attacks a facedown monster, can it activate its effect to destroy and inflict damage, or not, because the monster's atk would be unknown? I know the OCG has a ruling on this matter, but konami hasnt released that ruling for the TCG yet to my knowledge.... Tiamat dragon55 21:08, January 13, 2010 (UTC)
