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. Nidoqueen is H21/144, in position 171 of 182 on this checklist. Before it is H20 Moltres, and after it is H22 Piloswine. The listed rarity is Rare Holo.
Nidoqueen is a Stage 2 Grass Pokémon with 110 HP. In the Pokédex this is Nidoqueen (#031), generation 1 (Kanto). The card says it evolves from Nidorina. In this catalog that name is Nidorina (#030).
Mitsuhiro Arita illustrated this card. The same name is on 721 other cards in the catalog.
Nidoqueen (#031) has 18 other cards in the catalog. Those other cards are in 16 sets. The other printings with a release date run from 1999 to 2025. The earliest other card is Nidoqueen 7/64 in Jungle (1999). That card lists 90 HP, and this one lists 110 HP. Both list the rarity Rare Holo. Ken Sugimori illustrated that card, and Mitsuhiro Arita illustrated this one. 17 other cards of Nidoqueen list a different HP.
Evolution Helper is listed as Poké-Power. Once during your turn (before your attack), if Nidoqueen is on your Bench, you may search your deck for a card that evolves from your Active Pokémon and attach it to your Active Pokémon. (This counts as evolving that Pokémon.) Shuffle your deck afterward. The attack Double Claw lists 30+ damage. The cost is Grass, Colorless, Colorless. Flip 2 coins. This attack does 30 damage plus 20 more damage for each heads Weakness is Psychic ×2. Retreat cost is 3.
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. Nidoqueen can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
