Jungle is a set in the Base series. It was released on June 16, 1999. The printed size is 64, and the checklist is the same length. Clefable is 17/64, in position 17 of 64 on this checklist. Before it is 16 Wigglytuff, and after it is 18 Electrode. The listed rarity is Rare.
Clefable is a Stage 1 Colorless Pokémon with 70 HP. The card lists level 34. In the Pokédex this is Clefable (#036), generation 1 (Kanto). The card says it evolves from Clefairy. In this catalog that name is Clefairy (#035).
Mitsuhiro Arita illustrated this card. The same name is on 721 other cards in the catalog.
Clefable (#036) has 28 other cards in the catalog. Those other cards are in 25 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Clefable 1/64 in Jungle (1999). Both list 70 HP. The rarity there is Rare Holo, and here it is Rare. 23 other cards of Clefable list a different HP.
The attack Metronome lists no damage number. The cost is Colorless. Choose 1 of the Defending Pokémon's attacks. Metronome copies that attack except for its Energy costs and anything else required in order to use that attack, such as discarding Energy cards. (No matter what type the Defending Pokémon is, Clefable's type is still Colorless.) Minimize is another attack lists no damage number. The cost is Colorless, Colorless. All damage done by attacks to Clefable during your opponent's next turn is reduced by 20 (after applying Weakness and Resistance). Weakness is Fighting ×2. Resistance is Psychic -30. Retreat cost is 2. The flavor text reads "A timid Fairy Pokémon that is rarely seen. It will run and hide the moment it senses people."
I keep a set binder for Jungle, meant to hold every card of that set. This card is one slot in the Jungle set binder. A generation binder holds one card of each species. Clefable can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
