>A Pokémon League provides a nearby place for you to get together with other fans of both the Pokémon Trading Card Game and the Pokémon video games, and have some fun. Using your own cards and Pokémon DS games, you can play, trade, and even earn cool prizes! The best part is that you can do all this with other Pokémon players who love collecting and playing just as much as you do.
>Even if you don’t know all the rules of the game, at a league you can learn game basics and, in no time, perfect your strategy! Joining a league is the best way to hone your skills to compete in Pokémon tournaments from Battle Roads all the way up to the World Championships. Leagues are held in safe public locations, such as game stores, community centers, or libraries, and are run by official League Leaders.
