Swampert (#260) has 14 other cards in the catalog. Those other cards are in 10 sets. The other printings with a release date run from 2003 to 2021. The earliest other card is Swampert 13/109 in Ruby & Sapphire (2003). That card lists 110 HP, and this one lists 130 HP. Both list the rarity Rare Holo. Mitsuhiro Arita illustrated that card, and Kagemaru Himeno illustrated this one. Retreat cost there is 3, and here it is 2. 13 other cards of Swampert list a different HP.
The illustrator line reads Kagemaru Himeno. I count 656 other cards in the catalog with that illustrator.
Supreme Victors set binder is where a full Supreme Victors set goes. This card fills one slot there. A generation binder holds one card of each species. Swampert can fill a slot in Generation 3 binder (Hoenn). I still need this card.
