Whenever you attach a Lightning Energy card from your hand to Jolteon, remove all Special Conditions affecting Jolteon.

Skyridge is a set in the E-Card series. It was released on May 12, 2003. The printed size is 144. This checklist is longer, at 182 cards. Jolteon is H12/144, in position 162 of 182 on this checklist. Before it is H11 Houndoom, and after it is H13 Kabutops. The listed rarity is Rare Holo.
Jolteon is a Stage 1 Lightning Pokémon with 70 HP. In the Pokédex this is Jolteon (#135), generation 1 (Kanto). The card says it evolves from Eevee. In this catalog that name is Eevee (#133).
Hikaru Koike illustrated this card. The same name is on 46 other cards in the catalog.
Jolteon (#135) has 38 other cards in the catalog. Those other cards are in 29 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Jolteon 4/64 in Jungle (1999). Both list 70 HP. Both list the rarity Rare Holo. Kagemaru Himeno illustrated that card, and Hikaru Koike illustrated this one. 27 other cards of Jolteon list a different HP.
Self-healing is listed as Poké-Body. Whenever you attach a Lightning Energy card from your hand to Jolteon, remove all Special Conditions affecting Jolteon. The attack Thundershock lists 10 damage. The cost is Lightning. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Thunderspark is another attack lists 40 damage. The cost is Lightning, Colorless, Colorless. This attack does 10 damage to each Benched Pokémon with at least 1 Energy card attached to it (yours and your opponent's). Weakness is Fighting ×2.
I keep a set binder for Skyridge, meant to hold every card of that set. This card is one slot in the Skyridge set binder. A generation binder holds one card of each species. Jolteon can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Eevee and the Eeveelutions. I still need this card.
