Trading card games (TCGs) are games where players use specially designed cards to compete against each other. Each card represents a character, spell, or item, and players build their own decks by selecting cards from their collections. The goal is often to reduce an opponent's life points to zero or achieve specific objectives outlined in the game rules. Players can trade cards with each other to improve their decks and strategies. Popular examples of TCGs include Magic: The Gathering, Yu-Gi-Oh!, and Pokémon. These games often involve strategic thinking, planning, and sometimes luck, making them engaging for players of all ages.
