Swampert ex is a Stage 2 ex Fighting 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).
Hikaru Koike illustrated this card. The same name is on 46 other cards in the catalog.
Swampert (#260) has 14 other cards in the catalog. Those other cards are in 10 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 Hikaru Koike illustrated this one. 12 other cards of Swampert list a different HP.
The attack Hyper Pump lists 20+ damage. The cost is Colorless. Does 20 damage plus 20 more damage for each basic Energy attached to Swampert ex but not used to pay for this attack's Energy cost. You can't add more than 80 damage in this way. Crushing Wave is another attack lists no damage number. The cost is Water, Colorless, Colorless. Choose 1 of your opponent's Pokémon. This attack does 40 damage to that Pokémon. After doing damage, flip a coin. If heads, your opponent discards an Energy card, if any, attached to that 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 Team Magma vs Team Aqua, meant to hold every card of that set. This card is one slot in the Team Magma vs Team Aqua 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.
