How odd

We were playing a card game at home - a variation of slap jack where we call the cards from Ace to King and slap when the card matches the call. I have played this game lots of times and for the first time in my life, the whole deck was dealt and non of the cards matched! So what is the probability of a set of cards that does not match their ordinal position at all? I have to think about calculating that...
