Provenance

Where it came from

Walrein (39/123) was released as part of the Mysterious Treasures expansion of the Pokémon Trading Card Game, which debuted in 2007. This set was the second expansion in the Diamond & Pearl Series, introducing players to the mechanics and aesthetic shifts defined by the Sinnoh region's generation of Pokémon. As a stage 2 evolution, the card serves as a strategic water-type asset, reflecting the game's ongoing focus on evolving creature synergies during the mid-2000s.

The artwork for this specific card was illustrated by Mitsuhiro Arita, one of the most prolific and iconic contributors to the Pokémon TCG since its inception. Arita utilized a painterly style to capture the sturdy, arctic presence of Walrein, emphasizing its role as a powerful marine mammal. The design was well-received by players for its thematic consistency with the Diamond & Pearl game engine, providing a reliable evolution line that maintained the franchise's established visual identity during this era.
