2003 Pokemon Company / Nintendo Skyridge Ditto #51/144

This is Ditto (#51/144) from the 2003 Pokémon Skyridge set, illustrated by Tomokazu Komiya. Ditto features a Poké-Body called Prismatic Body — each basic Energy card attached to Ditto provides every type of Energy, but only 1 Energy at a time, making it a flexible and adaptive fighter. Its lone attack, Copy, lets Ditto mimic one of the Defending Pokémon's attacks, provided Ditto has the necessary Energy to do so. Ditto has a Darkness-type weakness, a Fighting-type resistance, and a retreat cost of one Colorless Energy. The card carries the e-Reader dot code along the left border, characteristic of the late e-Series era, and the ID code E-30-#. Illustrated against a cave-art backdrop featuring primitive Pokémon silhouettes, this is a beloved and mechanically unique card from one of the rarest English sets in the Pokémon TCG.
