Lanturn is Pokédex #171, generation 2 (Johto). Lanturn is a Stage 1 Lightning Pokémon with 80 HP. The card says it evolves from Chinchou. In this catalog that name is Chinchou (#170).
Lanturn sits at 15/108 in Power Keepers, position 15 of 108. Before it is 14 Dusclops, and after it is 16 Magneton. The set belongs to the EX series. It was released on February 2, 2007. The printed size is 108, and the checklist is the same length. The listed rarity is Rare.
Energy Grounding is listed as Poké-Power. Once during your opponent's turn, when any of your Pokémon is Knocked Out by your opponent's attacks, you may use this power. Choose a basic Energy card discarded from the Knocked Out Pokémon and attach it to Lanturn. You can't use more than 1 Energy Grounding Poké-Power each turn. The attack Lightning Strike lists 50 damage. The cost is Lightning, Lightning, Colorless. You may discard all Lightning Energy attached to Lanturn. If you do, this attack's base damage is 90 instead of 50. Weakness is Fighting ×2. Retreat cost is 2.
Lanturn (#171) has 25 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 2000 to 2024. The earliest other card is Lanturn 38/111 in Neo Genesis (2000). That card lists 70 HP, and this one lists 80 HP. The rarity there is Uncommon, and here it is Rare. Ken Sugimori illustrated that card, and Midori Harada illustrated this one. 16 other cards of Lanturn list a different HP.
The illustrator line reads Midori Harada. I count 352 other cards in the catalog with that illustrator.
Power Keepers set binder is where a full Power Keepers set goes. This card fills one slot there. A generation binder holds one card of each species. Lanturn can fill a slot in Generation 2 binder (Johto). I still need this card.
