Slowking

Once during your turn (before your attack), if Slowking is your Active Pokémon, you may have your opponent guess whether the top card of your deck is an Energy card, a Trainer card, or a Pokémon (Basic or Evolution) card. Flip the card over. If your opponent guessed right, discard the card. If your opponent guessed wrong, put the card into your hand. This power can't be used if Slowking is affected by a Special Condition.
