Zoroark (#571) has 40 other cards in the catalog. Those other cards are in 22 sets. The other printings with a release date run from 2011 to 2026. The earliest other card is Zoroark BW09/101 in BW Black Star Promos (2011). That card is named Zoroark, while this one is Zoroark-GX. That card lists 100 HP, and this one lists 210 HP. Both list the rarity Promo. Naoki Saito illustrated that card, and 5ban Graphics illustrated this one. Retreat cost there is 1, and here it is 2. 35 other cards of Zoroark list a different HP.
The illustrator line reads 5ban Graphics. I count 1,629 other cards in the catalog with that illustrator.
SM Black Star Promos set binder is where a full SM Black Star Promos set goes. This card fills one slot there. A generation binder holds one card of each species. Zoroark can fill a slot in Generation 5 binder (Unova). I still need this card.
