Elekid (#239) has 7 other cards in the catalog. Those other cards are in 7 sets. The other printings with a release date run from 2000 to 2023. The earliest other card is Elekid 22/111 in Neo Genesis (2000). That card lists 30 HP, and this one lists 40 HP. The rarity there is Rare, and here it is Uncommon. Miki Tanaka illustrated that card, and Kouki Saitou illustrated this one. 5 other cards of Elekid list a different HP.
The illustrator line reads Kouki Saitou. I count 652 other cards in the catalog with that illustrator.
Sandstorm set binder is where a full Sandstorm set goes. This card fills one slot there. A generation binder holds one card of each species. Elekid can fill a slot in Generation 2 binder (Johto). Themed lists that include this exact card are Baby Pokémon. I still need this card.
