Luxray (#405) has 26 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 2007 to 2026. The earliest other card is Luxray 7/130 in Diamond & Pearl (2007). Both list 120 HP. Both list the rarity Rare Holo. Mikiko Takeda illustrated that card, and Mitsuhiro Arita illustrated this one. 23 other cards of Luxray list a different HP.
The illustrator line reads Mitsuhiro Arita. I count 721 other cards in the catalog with that illustrator.
Legends Awakened set binder is where a full Legends Awakened set goes. This card fills one slot there. A generation binder holds one card of each species. Luxray can fill a slot in Generation 4 binder (Sinnoh). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
