Goldeen (#118) has 19 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Goldeen 53/64 in Jungle (1999). Both list 40 HP. Both list the rarity Common. Kagemaru Himeno illustrated that card, and Yuka Morii illustrated this one. 15 other cards of Goldeen list a different HP.

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. Goldeen can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Yuka Morii clay cards. I still need this card.
