Crystal Guardians is a set in the EX series. It was released on August 1, 2006. The printed size is 100, and the checklist is the same length. Swampert ex is 98/100, in position 98 of 100 on this checklist. Before it is 97 Shiftry ex, and after it is 99 Alakazam ★. The listed rarity is Rare Holo EX.
Swampert ex is a Stage 2 ex Water Pokémon with 150 HP. In the Pokédex this is Swampert (#260), generation 3 (Hoenn). The card says it evolves from Marshtomp. In this catalog that name is Marshtomp (#259).
Ryo Ueda illustrated this card. The same name is on 462 other cards in the catalog.
Swampert (#260) has 14 other cards in the catalog. Those other cards are in 11 sets. The other printings with a release date run from 2003 to 2021. The earliest other card is Swampert 13/109 in Ruby & Sapphire (2003). That card is named Swampert, while this one is Swampert ex. That card lists 110 HP, and this one lists 150 HP. The rarity there is Rare Holo, and here it is Rare Holo EX. Mitsuhiro Arita illustrated that card, and Ryo Ueda illustrated this one. 12 other cards of Swampert list a different HP.
Energy Recycle is listed as Poké-Power. Once during your turn (before your attack), you may search your discard pile for 3 Energy cards and attach them to your Pokémon in any way you like. If you do, your turn ends. This power can't be used if Swampert ex is affected by a Special Condition. The attack Ultra Pump lists 60+ damage. The cost is Water, Colorless, Colorless. You may discard 2 cards from your hand. If you do, this attack does 60 damage plus 20 more damage and does 20 damage to 1 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Grass ×2. 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 Crystal Guardians, meant to hold every card of that set. This card is one slot in the Crystal Guardians set binder. A generation binder holds one card of each species. Swampert can fill a slot in Generation 3 binder (Hoenn). I still need this card.
