POP Series 4

About this expansion

Released on July 31, 2006, POP Series 4 is the fourth promotional set in the Pokémon Organized Play (POP) series for the Pokémon Trading Card Game. It was distributed through Organized Play events and affiliated products and was the second POP series of promos to be made available at the Pokémon TCG World Championships. The cards were available to players during the 2006–2007 organized-play season (roughly August 2006 through March 2007) and were issued as event-specific promo content rather than a standard booster expansion.
