Though specific design elements of the court cards are rarely used in game play and many differ between designs, a few are notable. The Jack of Spades, Jack of Hearts, and King of Diamonds are drawn in profile, while the rest of the courts are shown in full face; these cards are commonly called "one-eyed". When deciding which cards are to be made wild in some games, the phrase "acey, deucey, one-eyed jack" (or "deuces, aces, one-eyed faces") is sometimes used, which means that aces, twos, and the one-eyed jacks are all wild. The King of Hearts is the only King with no mustache, and is also typically shown with a sword behind his head, making him appear to be stabbing himself. The axe held by the King of Diamonds is behind his head with the blade facing toward him. This leads to the nickname "suicide kings". The Jack of Diamonds is sometimes known as "laughing boy"[17]. The King of Diamonds is traditionally armed with an axe while the other three kings are armed with swords, and thus the King of Diamonds is sometimes referred to as "the man with the axe" because of this. This is the basis of the trump "one-eyed jacks and the man with the axe". The Ace of Spades, unique in its large, ornate spade, is sometimes said to be the death card, and in some games is used as a trump card. The Queen of Spades usually holds a scepter and is sometimes known as "the bedpost queen", though more often she is called "Black Lady". In many decks, the Queen of Clubs holds a flower. She is thus known as the "flower Queen", though this design element is among the most variable; the standard Bicycle Poker deck depicts all Queens with a flower styled according to their suit.
