Basic Pokémon are the foundation of all decks. Without them a player cannot play the game, since both players begin the game by placing a Basic Pokémon in the Active position on the field. Each Pokémon card depicts a Pokémon from the video games. Each player may have up to six Pokémon on the playing field at a time: one "Active" Pokémon and up to five on the bench. Each Pokémon card has a name, a type, and an amount of Health Points (HP). All Pokémon feature attacks; these typically deal damage to the opponent's active Pokémon, or occasionally, their benched Pokémon; however, an attack may also perform different functions, such as drawing cards, inflicting Special Conditions, or altering the opponent's board state. The vast majority of these attacks require Energy, which comes in the form of Energy cards. Abilities (known as Poké-Powers and Poké-Bodies until 2011) are not attacks but simply effects that either are activated under certain conditions, or remain in effect as long as the Pokémon with the Ability remains in play.
