Volcarona (#637) has 20 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 2011 to 2025. The earliest other card is Volcarona BW40/101 in BW Black Star Promos (2011). That card is named Volcarona, while this one is Volcarona-GX. That card lists 110 HP, and this one lists 210 HP. The rarity there is Promo, and here it is Rare Rainbow. Shin Nagasawa illustrated that card, and PLANETA Tsuji illustrated this one. 16 other cards of Volcarona list a different HP.
The illustrator line reads PLANETA Tsuji. I count 81 other cards in the catalog with that illustrator.
Cosmic Eclipse set binder is where a full Cosmic Eclipse set goes. This card fills one slot there. A generation binder holds one card of each species. Volcarona can fill a slot in Generation 5 binder (Unova). I still need this card.
