Diamond and Pearl – Stormfront is the 39th set of cards of the Trading Card Game and the 23rd released by Pokémon USA, and was released in November 2008. Its symbol is a circle with a lightning bolt running through it. It is a set of 100 cards. The set reintroduced Pokémon of alternate coloration (better known as shiny Pokémon) and was the first set of the Diamond and Pearl series to reprint three "classic" cards from the first Trading Card Game expansions. The set includes eight Pokémon LV.X, two of which were also released as promotional cards. It also introduced trainer cards that can be used with another one at the same time.
