Forum:Chain Disappearance vs Dupe Frog

Player A summons Dupe Frog, and Player B responds with Chain Disappearance. Are all Dupe Frogs removed from Player A's deck, or are all Des Frogs removed from play because Dupe Frog is treated as Des Frog when it is faceup on the field?Anush1 21:26, 23 July 2009 (UTC)
