Starmie is Pokédex #121, generation 1 (Kanto). Starmie is a Stage 1 Psychic Pokémon with 70 HP. The card lists level 31. The card says it evolves from Staryu. In this catalog that name is Staryu (#120).
Starmie sits at 25/64 in Neo Revelation, position 25 of 66. Before it is 24 Sneasel, and after it is 26 Sudowoodo. The set belongs to the Neo series. It was released on September 21, 2001. The printed size is 64. This checklist is longer, at 66 cards. The listed rarity is Rare.
The attack Confuse Ray lists 10 damage. The cost is Water. Flip a coin. If heads, the Defending Pokémon is now Confused. Core Stream is another attack lists no damage number. The cost is Psychic, Psychic, Colorless. Choose an Energy type other than Colorless. This attack does 20 damage to each of your opponent's Pokémon with any Energy cards of that type attached to it. Don't apply Weakness and Resistance. Weakness is Psychic ×2. Retreat cost is 1. The flavor text reads "The center section of its body is called the core. It glows in a different color each time it is seen."
Starmie (#121) has 34 other cards in the catalog. Those other cards are in 27 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Starmie 64/102 in Base (1999). That card lists 60 HP, and this one lists 70 HP. The rarity there is Common, and here it is Rare. Keiji Kinebuchi illustrated that card, and Keita Komatsuya, CR CG gangs illustrated this one. 31 other cards of Starmie list a different HP.
Keita Komatsuya, CR CG gangs illustrated Starmie, and no other card in this catalog uses that name.
Neo Revelation set binder is where a full Neo Revelation set goes. This card fills one slot there. A generation binder holds one card of each species. Starmie can fill a slot in Generation 1 binder (Kanto). I still need this card.
