This article is about a Japanese Pokémon Trading Card Game card which has not yet been officially released in English and, hence, may not be released outside of Japan. As such, this article may contain translated Japanese terms instead of English terms.
In Japan, this card was one of five Holofoil Unnumbered Promotional cards that could be obtained as part of the Communication Evolution Campaign. The campaign launched with the release of the third Expansion Sheet on November 24, 1998 and ran until April 30, 1999. Participants who mailed a copy of any Omanyte card along with a copy of Bill's PC to Media Factory during the campaign period were sent a copy of Omastar in return. Approximately 21,000 applications were made for Omastar, making it the least popular of the five cards available.
The requirement of Bill's PC for the campaign led to the five available cards to become known colloquially as Masaki promos in reference to Bill's Japanese name.
Cards from the Expansion Sheets are printed on glossy card stock, while those distributed as part of the Communication Evolution Campaign are printed on regular card stock.
Although the Communication Evolution Campaign cards are based on the concept that certain Pokémon have to be traded to evolve, Omastar's pre-evolved form, Omanyte, does not require to be traded in order to evolve in the Pokémon games.
