The earliest other card is Xerneas XY05/211 in XY Black Star Promos (2013). That card is named Xerneas, while this one is Xerneas-GX. That card lists 130 HP, and this one lists 180 HP. The rarity there is Promo, and here it is Rare Ultra. 20 other cards of Xerneas list a different HP.

I keep a set binder for Forbidden Light, meant to hold every card of that set. This card is one slot in the Forbidden Light set binder. A generation binder holds one card of each species. Xerneas can fill a slot in Generation 6 binder (Kalos). I still need this card.
