Dragon is a set in the EX series. It was released on November 24, 2003. The printed size is 97. This checklist is longer, at 100 cards. Ampharos ex is 89/97, in position 89 of 100 on this checklist. Before it is 88 TV Reporter, and after it is 90 Dragonite ex. The listed rarity is Rare Holo EX.
Ampharos ex is a Stage 2 ex Lightning Pokémon with 150 HP. In the Pokédex this is Ampharos (#181), generation 2 (Johto). The card says it evolves from Flaaffy. In this catalog that name is Flaaffy (#180).
Ryo Ueda illustrated this card. The same name is on 462 other cards in the catalog.
Ampharos (#181) has 37 other cards in the catalog. Those other cards are in 26 sets. The other printings with a release date run from 2000 to 2026. The earliest other card is Ampharos 1/111 in Neo Genesis (2000). That card is named Ampharos, while this one is Ampharos ex. That card lists 80 HP, and this one lists 150 HP. The rarity there is Rare Holo, and here it is Rare Holo EX. Ken Sugimori illustrated that card, and Ryo Ueda illustrated this one. Retreat cost there is 2, and here it is 3. 34 other cards of Ampharos list a different HP.
Conductivity is listed as Poké-Body. As long as Ampharos ex is in play, whenever your opponent attaches an Energy card to his or her Pokémon from hand, put 1 damage counter on that Pokémon. You can't put more than 1 damage counter even if there is more than 1 Ampharos ex in play. The attack Gigavolt lists 40+ damage. The cost is Lightning, Colorless, Colorless. Flip a coin. If heads, this attack does 40 damage plus 30 more damage. If tails, the Defending Pokémon is now Paralyzed. Weakness is Fighting ×2. Resistance is Metal -30. Retreat cost is 3. The card text says: When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.
I keep a set binder for Dragon, meant to hold every card of that set. This card is one slot in the Dragon set binder. A generation binder holds one card of each species. Ampharos can fill a slot in Generation 2 binder (Johto). I still need this card.
