Slowking is a Stage 1 Water Pokémon with 80 HP. In the Pokédex this is Slowking (#199), generation 2 (Johto). The card says it evolves from Slowpoke. In this catalog that name is Slowpoke (#079).
Kagemaru Himeno illustrated this card. The same name is on 656 other cards in the catalog.
Slowking (#199) has 25 other cards in the catalog. Those other cards are in 18 sets. The other printings with a release date run from 2000 to 2025. The earliest other card is Slowking 14/111 in Neo Genesis (2000). Both list 80 HP. The rarity there is Rare Holo, and here it is Rare. Ken Sugimori illustrated that card, and Kagemaru Himeno illustrated this one. Retreat cost there is 3, and here it is 1. 18 other cards of Slowking list a different HP.
Prize Shift is listed as Poké-Power. 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. The attack Psychic Option lists 20+ damage. The cost is Colorless, Colorless. 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. Weakness is Lightning ×2. Retreat cost is 1.
I keep a set binder for Delta Species, meant to hold every card of that set. This card is one slot in the Delta Species set binder. A generation binder holds one card of each species. Slowking can fill a slot in Generation 2 binder (Johto). I still need this card.
