Moltres (#146) has 43 other cards in the catalog. Those other cards are in 28 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Moltres 21/53 in Wizards Black Star Promos (1999). That card is named Moltres, while this one is Moltres ex. That card lists 70 HP, and this one lists 110 HP. The rarity there is Promo, and here it is Rare Secret. Toshinao Aoki illustrated that card, and Ryo Ueda illustrated this one. Retreat cost there is 1, and here it is 2. 43 other cards of Moltres list a different HP.
The illustrator line reads Ryo Ueda. I count 462 other cards in the catalog with that illustrator.
FireRed & LeafGreen set binder is where a full FireRed & LeafGreen set goes. This card fills one slot there. A generation binder holds one card of each species. Moltres can fill a slot in Generation 1 binder (Kanto). I still need this card.
