Return Deck To Its Original Form

The trick:  Brand new deck of cards, all inthe proper order by suit.

Spectator just thinks of any card.  They don;t pick and they dont tell you.  they just think

I shuffle cards and have them cut a few times.  Then you say, do you think it would be cool if i could make one magical cut and have your card return to the exact same spot it was before we did all the shuffling and cutting?  Voila: reveal:   all cards are in the exact same position

How its does:  have ace of spades at the bottom:  when you do you magic cut make sure the ace of spades. is on the bottom:  when you do magic cut, return the ace to the bottom and all the cards will be in the exact order they started in.
