Famous magicians Dylan Rhodes and Daniel Atlas performed an exhilarating magic trick in my last birthday party. Since, it was my birthday, Rhodes asked me to shuffle a new deck and pick any five cards out of it. I took out the cards as asked, looked at them and then showed all five cards to Rhodes. Rhodes then gave four cards to Daniel and the remaining fifth card to me. Daniel looked at the four cards for about ten seconds and then he told me what card I was holding.

Surprise, Surprise! He was right!

It was quite surprising to me at that time, but when I reached back home, I was able to crack the trick behind the magic.

Can you?
