Shelgon (#372) has 17 other cards in the catalog. Those other cards are in 14 sets. The other printings with a release date run from 2003 to 2025. The earliest other card is Shelgon 20/97 in Dragon (2003). That card lists 80 HP, and this one lists 90 HP. The rarity there is Rare, and here it is Uncommon. Mitsuhiro Arita illustrated that card, and Tomokazu Komiya illustrated this one. 15 other cards of Shelgon list a different HP.
The illustrator line reads Tomokazu Komiya. I count 248 other cards in the catalog with that illustrator.
Stormfront set binder is where a full Stormfront set goes. This card fills one slot there. A generation binder holds one card of each species. Shelgon can fill a slot in Generation 3 binder (Hoenn). I still need this card.
