The mucked cards don't change much...people like to argue that if everyone folds the odds of aces being delt are higher. This is very insignificant. Have you ever seen someone use this in a poker game? "hmm i have KK but an ace flopped. I fold because 7 other people folded preflop meaning they must not have had an ace so the odds are higher that villain has one." Also, this shouldn't even come into play if we are dealing with a flush becuase people won't change their preflop ranges based on if it is AKspades or AKhearts.

Having duplicate cards in the deck doesn't change the odds unless they are delt. If you took the deck before the flop is delt and stuck a bunch of new cards on the bottom--it wouldn't change the flop because they aren't going to be used. This same logic works if you shuffle a bunch of new cards into a deck. They don't change the odds unless they come into play.

Even though the odds aren't changed if you are playing in a casino i think they will still cancel the hand.
