Mystery Plate Y is a first-edition Japanese Trainer card from the 2002 Split Earth expansion – the Japanese counterpart to the English Skyridge set – of the Pokémon trading card game. The card’s artwork shows a mysterious glowing metal plate in a mossy cave, rendered in a detailed, atmospheric style that echoes the set’s theme of ancient ruins and technology. A gold-bordered holographic pattern and bold rarity symbol highlight its foil treatment, making this card especially eye-catching for collectors. Its early e-Reader era design (complete with the 1st-edition stamp) and versatile trainer effect give Mystery Plate Y both nostalgic appeal and play value, making it a distinctive piece for any Pokémon TCG collection.
