Tangela (#114) 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 Tangela 66/102 in Base (1999). That card is named Tangela, while this one is Koga's Tangela. Both list 50 HP. Both list the rarity Common. Mitsuhiro Arita illustrated that card, and Atsuko Nishida illustrated this one. 26 other cards of Tangela list a different HP.
The illustrator line reads Atsuko Nishida. I count 408 other cards in the catalog with that illustrator.
Gym Challenge set binder is where a full Gym Challenge set goes. This card fills one slot there. A generation binder holds one card of each species. Tangela can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Trainer's Pokémon, Atsuko Nishida cards, early series, Kanto Gym Leaders and their Pokémon, and Nap time. I still need this card.
