Forum:Mystic wok vs soul exchange

Since Mystic Wok Looks at the current attack, or current defense of the monster tributed, If you used soul exchange on your opponent's face-down monster card and then activated mystic wok to tributed, since it was still face-down on your opponent side of the field it would not matter if you select atk or def since the current atk and def was unknown you would receive 0 life points from mystic wok is this correct?S.nickid (talk • contribs) 13:19, March 21, 2015 (UTC)
