Collapse of Time & Space is the third Korean extension set of cards after the Pokémon Trading Card Game went into hiatus until the middle of 2010. Released August 26, 2010, this extension set continues to introduce both new Generation IV Pokémon and new Pokémon LV.X in the Korean Card Game. In order to give the players what was missing from the previous set, this set focuses on releasing Psychic-type, Fighting-type, Darkness-type, and Metal-type cards.
Included in the Collapse of Time and Space set are 60 cards originating from the early half of the English Diamond & Pearl Series. The set pulls its Pokémon LV.X from the Great Encounters and Legends Awakened expansions, but contains a majority of cards from the Diamond & Pearl and Legends Awakened expansions.
The only three Legendary Pokémon included in the set are Palkia, Dialga, and Giratina. Palkia and Dialga are included twice (Palkia and Palkia LV.X, Dialga and Dialga LV.X). Darkness Energy and Metal Energy premier in this extension.
