Why is joker in a pack of cards a superstition?

The Joker in a pack of cards is often considered a symbol of superstition because it represents chance, unpredictability, and the idea of the wild card, which can alter the outcome of a game. Its origins are linked to the game of Euchre, where it was introduced as a trump card, embodying luck and the unknown. Many believe that drawing a Joker can bring either good or bad fortune, reinforcing its association with superstition in gambling and card games.
