The earliest other card is Aggron 1/109 in Ruby & Sapphire (2003). That card lists 110 HP, and this one lists 180 HP. The rarity there is Rare Holo, and here it is Uncommon. Mitsuhiro Arita illustrated that card, and Dsuke illustrated this one. Retreat cost there is 4, and here it is 3. 19 other cards of Aggron list a different HP.
The illustrator line reads Dsuke. I count 13 other cards in the catalog with that illustrator.
Twilight Masquerade set binder is where a full Twilight Masquerade set goes. This card fills one slot there. A generation binder holds one card of each species. Aggron can fill a slot in Generation 3 binder (Hoenn). I still need this card.
