Team Rocket arrived in 2000 as one of the Pokemon TCG's most memorable sets, introducing the concept of "Dark" Pokemon—corrupted versions of familiar creatures with reversed alignment. The set captured the franchise's darker edge while maintaining broad appeal, becoming a cornerstone of early 2000s collecting. First Edition copies remain especially sought after, representing the initial print run before Team Rocket's eventual reprints. Dark Blastoise stands among the set's most iconic cards, depicting the water-type powerhouse in its shadowy form. Collectors prize Dark Blastoise for its striking artwork and the card's role as a centerpiece of Dark-themed competitive decks, making it a defining piece of Team Rocket's legacy and a gateway card for many collectors exploring the set's mythology.
