Neo Revelation, released in October 2001, is the 11th set of 64 cards in the Pokémon Trading Card Game. Its symbol is a representation of the departure of Suicune, Entei and Raikou from the Burned Tower.
As of the release of this set, there were at least one card of each of the 251 Pokémon, including the elusive Celebi. This set finishes the second generation with Pokémon like Porygon2, Misdreavus, and Raikou. In a way, this makes it a counterpart to the Fossil set (which rounded out the original set of 151 Pokémon). It also includes three more of the Unown introduced in Neo Discovery.
Most importantly, this set was the debut of the Shiny Pokémon. Shining Pokémon are extremely powerful, but no more than one of each kind is allowed in a deck. This tradition was short-lived, however, as the Shining Pokémon were present only until the following set, Neo Destiny. However, Pokémon Star cards, which function almost identically to Shining Pokémon, were introduced in a later set known as EX Team Rocket Returns.
