Talk:Blackjack

I have a question - does the deck actually contain 52 cards or is it randomly generated each time [.e.g if I see a king of hearts, could I get a king of hearts the next five hands (implying that the deck is "shuffled" in the game after each hand) or will it not appear until either a new deck is used or the king of hearts reappears once the deck is done]? The reason I want to know is because I'd like to know if I can count cards successfully.
