Pokémon TCG Mystery Plate (Δ) is a 1st Edition Japanese Trainer (Technical Machine) card from the Split Earth (裂けた大地) expansion released in 2002. This Uncommon (◆) trading card features original artwork by Hiromichi Sugiyama—a glowing golden tablet suspended over a verdant oasis under ethereal green light. It has a regular (non-holo) finish with the 1st Edition stamp in Japanese text, giving it a nostalgic collector’s feel from the e-Card era. Notably, Mystery Plate Δ is one of four “Mystery Plate” plates (α, β, γ, δ) unique to the Split Earth set, making this Pokémon card a sought-after piece for collectors completing the expansion.
