Card Rulings:Emblem of Dragon Destroyer

OCG Rulings

 * You can activate "Emblem of the Dragon Destroyer", etc, while "Thunder King Rai-Oh" is face-up on the field. When resolving the effect, if "Thunder King Rai-Oh" is on the field, then you can only add a "Buster Blader" from your Graveyard to your hand.
