Mysterious Treasures (TCG)

Diamond & Pearl: Mysterious Treasures (Japanese: 湖の秘密 Secret of the Lakes) is the name given to the second expansion of cards of the Diamond & Pearl era of the Trading Card Game.

Information

 * Mysterious Treasures is based on the Sinnoh Legendary trio,, and , hence the Japanese name The Lakes' Secret as these Pokémon reside at the bottom of Sinnoh's lakes.
 * Like TCG EX Sandstorm (which was also the second expansion for its particular generation (III)), Mysterious Treasures introduces the two Fossil Pokémon introduced in Generation IV in card form. The new rule regarding Fossil cards first announced with the release of TCG Diamond & Pearl applies to the new Skull and Armor Fossil cards released in this set.
 * Mysterious Treasures also introduces Pokémon that come with held items; in this case Berries. These held items work in the same fashion as Poké-Bodies, in that the effect the item provides is active whenever the Pokémon is in play. This is another game mechanic derived from the games, in that some wild Pokémon are holding an item when they are caught.
 * Mysterious Treasures features the secret card, which was previously only available as a Japanese promotional card at Battle Road Spring 2007. Like its Japanese counterpart it features a holographic border, making this the first English Trainer card to have this treatment. It is also the first secret card included in a set since TCG EX Holon Phantoms.
 * Although there are cards for TCG Abra and TCG Alakazam, there is no TCG Kadabra; one of Abra's attacks allows it to evolve straight to Alakazam. The noticeable exclusion of Kadabra is likely a result of the controversy.
 * The prerelease card for this set is.
