Mysterious Treasures

The Pokémon TCG: Mysterious Treasures set was released in the United States on August 15th, 2007. The set contains 143 cards, including 102 cards from the Japanese Secret of the Lakes set and the remaining 41 cards from either from other Japanese sets or created specifically for this set. This set is the 11th set in the Pokémon TCG and introduces the Legendary Rayquaza from the fourth generation of the Pokémon video games. The set also contains a variety of powerful new cards, including Rare Candy, Groudon, Deoxys, and Tyranitar.

The set has three types of cards: Pokémon cards, Trainer cards, and Energy cards. Each card is given a rarity designated by a symbol indicating which type of card it is; Common, Uncommon, Rare, or Ultra-Rare. The card rarities are important because they determine which cards can be used in a deck. The set mainly focuses on two of the main Pokémon types: Fire and Water. These two types are used in several cards in the set, which takes place in a desert area with a mysterious energy source.
