AttackEnergy Shower
Attach any number of basic Energy cards from your hand to your Pokémon in any way you like.

Flygon is Pokédex #330, generation 3 (Hoenn). Flygon is a Stage 2 Colorless Pokémon with 120 HP. The card says it evolves from Vibrava. In this catalog that name is Vibrava (#329).
Flygon sits at 4/97 in Dragon, position 4 of 100. Before it is 3 Crawdaunt, and after it is 5 Golem. The set belongs to the EX series. It was released on November 24, 2003. The printed size is 97. This checklist is longer, at 100 cards. The listed rarity is Rare Holo.
The attack Energy Shower lists no damage number. The cost is Grass, Lightning. Attach any number of basic Energy cards from your hand to your Pokémon in any way you like. Rainbow Burn is another attack lists 30+ damage. The cost is Colorless, Colorless, Colorless. Does 30 damage plus 10 more damage for each type of basic Energy card attached to Flygon. Weakness is Colorless ×2. Resistance is Fire -30 and Lightning -30. Retreat cost is 2.
Flygon (#330) has 27 other cards in the catalog. Those other cards are in 20 sets. The other printings with a release date run from 2003 to 2025. The earliest other card is Flygon 25/40 in Nintendo Black Star Promos (2003). Both list 120 HP. The rarity there is Promo, and here it is Rare Holo. Kouki Saitou illustrated that card, and Mitsuhiro Arita illustrated this one. 23 other cards of Flygon list a different HP.
The illustrator line reads Mitsuhiro Arita. I count 721 other cards in the catalog with that illustrator.
Dragon set binder is where a full Dragon set goes. This card fills one slot there. A generation binder holds one card of each species. Flygon can fill a slot in Generation 3 binder (Hoenn). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
