The earliest other card is Metagross 11/101 in Hidden Legends (2004). That card is named Metagross, while this one is Metagross ex. That card lists 100 HP, and this one lists 150 HP. The rarity there is Rare Holo, and here it is Rare Holo EX. Kouki Saitou illustrated that card, and Mitsuhiro Arita illustrated this one.

The illustrator line reads Mitsuhiro Arita. I count 721 other cards in the catalog with that illustrator.
Hidden Legends set binder is where a full Hidden Legends set goes. This card fills one slot there. A generation binder holds one card of each species. Metagross can fill a slot in Generation 3 binder (Hoenn). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
