How to Perform the "auto-reversal" trick
1.This video describes how to perform the auto reversal trick. Take a seat on the rocking chair of magic. To do this magic you are going to need regular deck of cards of 52 and you can have the joker, also it doesn't matter. Before you keep the cards in hands you have to do little setup that is turn down the bottom most card to face up.
2. So the bottom most card will face up and rest of the cards will face down. Spread the cards and let them choose any card. It doesn't matter what type of card it is. After the card is selected for example in this case 9 of hearts is taken, and while you focus the audience by showing that card in the right hand you just turn the entire deck of cards by hiding your left hand behind the leg and now one card will look face down and rest of all will face up.
3.Now show the cards and place that selected card, 9 of hearts in the center of the deck and do not let the card spread out while inserting the card into center otherwise they will see the fact. Finally take the cards to behind your back and use your one to turn the top of the card to "face up" and it should be done as quick as possible, if it is difficult to do this just use your two hands to turn it and take your time.
4. Now you spread the cards and only one card will look face down which the card what is that is why I turn the top of the card to face up. So, we take that card which is face down and first look at the card yourself and slowly turn it to audience to keep them in suspense.
