Can't really be used in any card games known to me, but I think it is for a joke
There are usually two joker cards in a deck of playing cards. They can used to replace a damaged, soiled or lost playing card or included in games like Old Maid.
A regular 52-card deck of cards is used when playing bridge. The extra two joker cards are discarded. Two sizes are available, the poker deck or the slightly narrower bridge deck.

In an ordinary deck of playing cards (such as used in solitaire or poker) the suits are called hearts, clubs, diamonds, and spades. The face cards are king (K), queen (Q) and joker (J). Then there are the numbers 2-10. The "one" card is called an ace (A) and can be the lowest or the highest in value, depending on the game being played.
In casino games jokers are not used in poker games. In private or home games a joker can be substituted for any card in the deck.
shuffled can be used as a deck of cards "the dealer shuffled the deck of cards before dealing the game of poker"
In a single-deck-game there are 52 cards. In a 6-deck-game there are 312 cards.
In a standard deck of 52 cards every card is different. There are four suits: spades, hearts, diamonds and clubs. Each suit has 13 cards, from one (the ace) to 10, plus a jack, queen and king. Therefore there are four different kings: a king of spades, a king of hearts, etc. The same for all the others: 4 different queens, four different jacks, etc.
No joker cards are used in Texas Hold'Em poker.
Cribbage uses a standard deck of cards.
