The earliest other card is Shelmet 10/108 in Dark Explorers (2012). Both list 60 HP. Both list the rarity Common. Shigenori Negishi illustrated that card, and Midori Harada illustrated this one. 3 other cards of Shelmet list a different HP.

Noble Victories set binder is where a full Noble Victories set goes. This card fills one slot there. A generation binder holds one card of each species. Shelmet can fill a slot in Generation 5 binder (Unova). I still need this card.
