No two backyards are the same and each game court is custom designed, it is difficult to say with certainty how long it will take. It depends on weather, access, terrain, permits, HOA approvals, and so on.
There are 52 cards in a deck, if you include the wild cards(joker), 54. In 52 cards there are 13 ranks and 4 suits, having the Ace as the highest in most card games. The suits are Diamonds,Clubs,Hearts and Spade. Standard card decks usually have Hearts and Diamond in Red and Clubs and Spades in Black.
There are four Kings, four Queens and four Jacks. one for each of the four suits in a normal deck, therefore in a bridge or poker deck there are 12 face cards. If you are using a double pinochle deck then this answer does not apply.
