Pokémon Trading Card Game Online — a simulation of a tabletop trading card game with role-playing game elements, similar to the main Pokémon series of role-playing games. Players challenge non-player characters and other online players to card battles using 60-card decks.
In Trainer Challenge mode, the player competes against a series of computer-controlled characters using pre-built themed decks. Winning several matches brings card boosters. This is one of the easiest modes in the game, so it is recommended for new players.
