Sabrina's Jynx sits at 59/132 in Gym Heroes, position 59 of 132. Before it is 58 Sabrina's Haunter, and after it is 60 Sabrina's Slowbro. The set belongs to the Gym series. It was released on August 14, 2000. The printed size is 132, and the checklist is the same length. The listed rarity is Uncommon.
The attack Good Night lists 10 damage. The cost is Psychic. The Defending Pokémon is now Asleep. Good Morning is another attack lists 20 damage. The cost is Psychic, Colorless. If the Defending Pokémon was Asleep, it is no longer Asleep. Weakness is Psychic ×2. Retreat cost is 1.
Jynx (#124) has 26 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 Jynx 31/102 in Base (1999). That card is named Jynx, while this one is Sabrina's Jynx. That card lists 70 HP, and this one lists 60 HP. Both list the rarity Uncommon. Retreat cost there is 2, and here it is 1. 21 other cards of Jynx list a different HP.
The illustrator line reads Ken Sugimori. I count 1,112 other cards in the catalog with that illustrator.
Gym Heroes set binder is where a full Gym Heroes set goes. This card fills one slot there. A generation binder holds one card of each species. Jynx can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Kanto Gym Leaders and their Pokémon, and Sabrina and her Pokémon. I still need this card.
