"Choose 1 card from your opponent's hand without looking. Look at the card you chose, then have your opponent shuffle that card into his or her deck."
If your opponent has no cards in his or her hand, do you still shuffle their deck? I know you still shuffle for Copycat if you have no cards in your hand, so I'm not sure if this is the same way.
