This is a beginner's guide to understanding the three fundamental card types that form every Pokémon Trading Card Game deck: Pokémon, Trainer, and Energy cards. The guide explains how each card type functions within the game's rules and why understanding their distinctions is essential for players wishing to build competitive decks and enjoy this long-running, highly popular card game.

Pokémon cards form the core of any deck and include Basic Pokémon (playable directly) and their evolved forms, with some variants like ex Pokémon offering higher HP and special abilities. Trainer cards are divided into two subcategories: Item cards (unlimited per turn) and Supporter cards (one per turn only), along with rare ACE SPEC cards (one per deck maximum) that are typically powerful variants of Item or Supporter types. Energy cards enable Pokémon to attack and retreat, with players able to attach only one Energy card per turn to their active Pokémon or bench, unless Trainer cards or Pokémon abilities grant additional attachments.
