The four kings in a deck of cards represent real rulers. The King of Diamonds shows Julius Caesar, the King of Clubs displays Alexander the Great, the King of Spades depicts David of Israel, and finally the King of Hearts shows Charles of France.
Every time you shuffle a deck of cards you are making history by creating a new unique order of cards that has never existed before. If all the approximately 6 billion people on Earth began shuffling a deck of playing cards one time per second for the next 100 billion years we would not even come close to fulfilling all possible card combinations.
Every time you shuffle a deck of cards, you are almost certainly creating an arrangement which the Universe has never before seen.
