Downcard is a term commonly used in card games such as poker to refer to a card that is dealt face down. As such, some synonyms for downcards would be facedown cards, hole cards, or pocket cards. Additionally, in games like blackjack, where the dealer has a facedown card, synonyms might include hidden card, face-down card, or undercard. In more casual games, players might refer to these cards simply as the cards they hold facing down. Regardless of the specific term used, downcards play an important role in many card games and are often crucial to successful play.
