Team Rocket arrived in 2000 as Pokemon TCG's first expansion celebrating the villainous organization. The set marked a creative pivot from earlier releases, introducing a darker aesthetic and alternate artwork that challenged the franchise's typically heroic tone. Team Rocket cards remain foundational to the hobby, representing an era when Pokemon trading cards were at peak cultural relevance and experimentation. Goop Gas Attack captures the set's mischievous spirit through its depiction of a Koffing attack. Collectors appreciate this card for its thematic artwork and its role in competitive and casual play during the early 2000s. As part of Team Rocket's iconic lineup, it holds nostalgic appeal for players who experienced the set's original release.
