There are 54 cards in a deck of playing cards, including 2 kings and 2 kings, including four suits: spades, clubs, hearts, and diamonds, and each suit has 13 cards. This is common sense that almost everyone knows.
Among the many types of decks, there is one that is quite special, and that is one way forcing deck.
As you can intuitively understand from its name, forced selection means that the entire deck of cards is composed of digital cards of the same suit. It is often used in card draft play, or as a consumable for signature cards to serve as a back-up deck when needed.
