Gym Heroes arrived in 2000 as one of the earliest Pokémon Trading Card Game expansion sets to spotlight Gym Leaders. The set captured a pivotal moment in the TCG's growth, introducing a fresh competitive focus and redesigned card mechanics that energized collectors and players alike. Pre-release promos from this era remain sought-after markers of the game's formative years. Misty's Seadra represents one of the set's most recognizable character cards, celebrating the beloved Water-type trainer. The holo treatment and artwork showcase Seadra in dynamic form, making this promo particularly appealing to both Pokémon enthusiasts and Misty fans. Character-specific cards from this generation continue to hold special appeal for collectors building thematic collections.
