Abilities
Prize Shift
Once during your turn (before your attack), you may choose a card from your hand and put it as a Prize card face up. If you do, choose 1 of your face-down Prize cards without looking and put it into your hand. This power can't be used if Slowking is affected by a Special Condition or if all of your Prize cards are face up.
Attacks
20+Psychic Option
If Slowking has a Water Energy card attached to it, this attack does 20 damage plus 20 more damage. If Slowking has a Psychic Energy card attached to it, discard a Special Energy card attached to the Defending Pokémon, if any.
