Background
Japanese Blastoise ex Special Art Rare 202/165 is a 2023 chase from SV2a Pokémon Card 151, the enhanced pack that reprinted the original 151 as a modern set. Mitsuhiro Arita drew the full-art Water starter in a moving pose; the set date in the source is 15 June 2023.
The card is a Stage 2 Water-type with 330 HP and the Solid Shell Ability that cuts attack damage taken. Inside 151 it sits above the Double Rare and Super Rare Blastoise prints as the SAR, which is why binders treat 202/165 as the Kanto water-starter picture, not the play reprint.
Desk notes stay on Arita, the 151 anniversary pack, and the SAR number. Grade-chase talk is left outside the story.
