The earliest other card is Qwilfish 127/165 in Expedition Base Set (2002). Both list 60 HP. Both list the rarity Common. Toshinao Aoki illustrated that card, and Sumiyoshi Kizuki illustrated this one. 10 other cards of Qwilfish list a different HP.
The illustrator line reads Sumiyoshi Kizuki. I count 212 other cards in the catalog with that illustrator.
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. Qwilfish can fill a slot in Generation 2 binder (Johto). I still need this card.
