Trainer cards are a fundamental component of the Pokémon Trading Card Game (TCG), designed to support and enhance gameplay by providing various effects that can aid players during battles. Unlike Pokémon cards, which represent the creatures themselves, Trainer cards represent items, supporters, tools, and environments within the Pokémon universe.

Trainer cards are indispensable tools in the Pokémon TCG that provide a myriad of effects to support players in various ways. Mastery of their use, understanding their limitations, and integrating them effectively into deck strategies are essential skills for any Pokémon TCG player.
