Pokémon Card Laboratory is a Stadium Trainer card from the Japanese “Battle Road Summer 2004” promotional series of the Pokémon TCG. Illustrated by Katsura Tabata, the card depicts a sleek high-tech research lab with computer stations and equipment, and a PCL (Pokémon Card Laboratory) sign on the wall – all framed by a metallic silver Trainer label border. Issued only as a prize to winners at Japan’s Summer 2004 Battle Road tournaments, this limited-edition Stadium promo has strong nostalgic appeal and rarity that collectors prize. Its unique Stadium effect – a card-guessing mini-game – adds an engaging strategic twist, making this promo card a distinctive addition to any Pokémon trading card collection or deck.
