| ||Details: The Base Set, released in January 1999, was the first set to be released, and the only one so far not to have a set logo or symbol. It is one of few sets to include Fighting, Fire, Grass, Lightning, Psychic and Water Energy cards, now commonly known as basic Energy cards. The set also contained Double Colorless Energy, the first Special Energy card. The set is one of the more well-rounded sets available, with a mixed amount of Pokémon of all types, and includes Pokémon that were more popular at the time of release, such as Charizard, Blastoise, Venusaur and Pikachu. The set's four main theme decks were represented by Ninetales, Mewtwo, Gyarados and Hitmonchan, and its starter set theme deck by Machamp.
