Base Set 2 is a set in the Base series. It was released on 24 February 2000. The printed size is 130, and the checklist is the same length. Blastoise is 2/130, in position 2 of 130 on this checklist. Before it is 1 Alakazam, and after it is 3 Chansey. The listed rarity is Rare Holo.
Blastoise is a Stage 2 Water Pokémon with 100 HP. The card lists level 52. In the Pokédex this is Blastoise (#009), generation 1 (Kanto). The card says it evolves from Wartortle. In this catalog that name is Wartortle (#008).
Ken Sugimori illustrated this card. The same name is on 1,112 other cards in the catalog.
Blastoise (#009) has 44 other cards in the catalog. Those other cards are in 26 sets. The other printings with a release date run from 1999 to 2024. The earliest other card is Blastoise 2/102 in Base (1999). Both list 100 HP. Both list the rarity Rare Holo. 39 other cards of Blastoise list a different HP.
Rain Dance is listed as Pokémon Power. As often as you like during your turn (before your attack), you may attach 1 Water Energy card to 1 of your Water Pokémon. (This doesn't use up your 1 Energy card attachment for the turn.) This power can't be used if Blastoise is Asleep, Confused, or Paralyzed. The attack Hydro Pump lists 40+ damage. The cost is Water, Water, Water. Does 40 damage plus 10 more damage for each Water Energy attached to Blastoise but not used to pay for this attack's Energy cost. You can't add more than 20 damage in this way. Weakness is Lightning ×2. Retreat cost is 3. The flavor text reads "A brutal Pokémon with pressurized water jets on its shell. They are used for high-speed tackles."
I keep a set binder for Base Set 2, meant to hold every card of that set. This card is one slot in the Base Set 2 set binder. A generation binder holds one card of each species. Blastoise can fill a slot in Generation 1 binder (Kanto). I still need this card.
