Great Encounters is a set in the Diamond & Pearl series. It was released on February 1, 2008. The printed size is 106, and the checklist is the same length. Swampert is 9/106, in position 9 of 106 on this checklist. Before it is 8 Sceptile, and after it is 10 Tangrowth. The listed rarity is Rare Holo.
Swampert is a Stage 2 Water Pokémon with 130 HP. The card lists level 53. 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).
Kouki Saitou illustrated this card. The same name is on 652 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 lists 110 HP, and this one lists 130 HP. Both list the rarity Rare Holo. Mitsuhiro Arita illustrated that card, and Kouki Saitou illustrated this one. Retreat cost there is 3, and here it is 2. 13 other cards of Swampert list a different HP.
Wash Out is listed as Poké-Power. As often as you like during your turn (before your attack), you may move a Water or Fighting Energy attached to 1 of your Benched Pokémon to your Active Pokémon. This power can't be used if Swampert is affected by a Special Condition. The attack Hammer Arm lists 80 damage. The cost is Water, Water, Colorless, Colorless. Discard the top card from your opponent's deck. Weakness is Grass +30. Retreat cost is 2. The flavor text reads "It can swim while towing a large ship. It bashes down foes with a swing of its thick arms."
I keep a set binder for Great Encounters, meant to hold every card of that set. This card is one slot in the Great Encounters 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.
