The term 'Deck Component' can be summarized as a four-letter word: 'CARD'. A CARD is a thin, flat piece of material, usually paper or plastic, used for playing games, writing messages, or other forms of communication. Cards are often used in board games, CARD games, and trading CARD games. They are also used in educational activities, such as flashcards, and in business, such as credit cards. Cards are an essential component of any deck, and they come in many different shapes, sizes, and colors.
