Set Details
Seek New Pokémon and You Shall Find… Mysterious Treasures
The search for new Pokémon continues! In Mysterious Treasures, you’ll catch the next wave of brand-new Pokémon that no Trainer has ever caught before. You’ll find new gameplay options like Pokémon with Berries, new Fossils, more powerful Pokémon LV.X, and attacks that will change the way every Trainer plays. You will treasure the power when you play the Pokémon TCG: Diamond & Pearl—Mysterious Treasures expansion!
Launched in English on August 22 2007 (Japan: March 2 2007 as Secret of the Lakes), the Mysterious Treasures Pokémon set serves as the second installment of the Diamond & Pearl Series. Its 123‑card core list—plus the secret‑rare Time‑Space Distortion (124/123)—dives into the lore of Sinnoh’s three lake guardians, Uxie, Mesprit, and Azelf, while expanding the LV.X roster with heavy hitters such as Lucario LV.X, Garchomp LV.X, and Honchkrow LV.X. Booster wrappers spotlight Dialga, Garchomp, Electivire, and Mismagius, each hinting at the ancient relics and hidden powers waiting inside every ten‑card pack.
Mechanically, Mysterious Treasures pushed the game in fresh directions. It introduced Pokémon that come into play holding an item—a passive effect that remains active as long as the Pokémon stays on the field, echoing the video‑game mechanic. The set also refined the newly minted LV.X concept: Level‑Up Pokémon inherit every attack and Poké‑Power from the Stage below, then layer on devastating new abilities—Lucario LV.X’s “Stance” grants a turn of total invulnerability, while Garchomp LV.X’s “Dragon Pulse” can pepper an opponent’s bench with counters. Trainers weren’t left out either; Fossil Excavator streamlined prehistoric decks, and Time‑Space Distortion became an instant staple thanks to its chance to rescue Pokémon directly from the discard pile.
Collectors still savor the quirks buried in the set. Time‑Space Distortion is one of the few secret‑rare Trainers printed with a full‑holo surface, and early runs feature a faint cosmic swirl pattern that variant hunters prize. Several commons—most famously Magikarp 89/123—appear with slightly darker watermarks on first‑wave sheets, creating subtle print‑run distinctions. Finally, each of the lake guardian holos hides a silhouette of its respective cavern in the background foil, a nod to the trio’s mythology that many players miss on first inspection. From competitive innovation to hidden artistry, Mysterious Treasures lives up to its name by packing both gameplay depth and collectible surprises into every emerald‑green booster.
