Please give me a super simple magic trick that only needs a deck of playing cards, and it should be surprising! ! Written expression. . thank you

This is a magic that requires arithmetic.

Magical steps:

1) Let the audience choose any number from 1 to 10, and then shuffle the cards.

2) The magician turns around and asks the audience to count down from the top of the playing card, checking the contents of the card, but don't move.

3) The audience handed the card to the magician (or turned his back on him). The magician turned the cards from top to bottom, completely reversed the order and put them back on the top.

4) The magician turned and asked the audience what the number was. Count from the last digit of the number said by the audience (for example, if the audience says 5, the first card will count from 6). Deal one card at a time. When the number reaches 20, turn it over This card is the correct answer.

Introduction to magic:

This is a good skill and easy to operate, but it can only be successful when your audience is absent-minded

Magical steps:

1) First of all, the bottom two cards cannot have the same number of points. In addition, it should be two black cards or one black card and one red card. Suppose it's eight diamonds and seven spades.

2) The top cards and top cards of these two cards should have the same number of points and suit as the other card. For example, the top cards of diamonds 8 and spades 7 should be diamonds 7 or spades 8, and the top cards should be spades 8 or spades 7.

3) Shuffle the cards, but don't change the position of the prepared cards.

4) Hold the card vertically with the thumb of the left hand and the other four fingers, with the thumb of the right hand at the bottom of the card stack and the other fingers at the top of the card stack. Drag the top card backwards with your right finger until the audience stops.

5) After the audience stops, quickly draw out the cards that have been dragged back, and at the same time drag the cards out with the thumb of the right hand to make them appear at the bottom of the right hand card stack.

6) Turn this card over (it should be 8 diamonds or 7 spades, of course) and give it to the audience. At the same time, put all the cards away and let the audience insert them into the stack.

7) Repeat steps 3, 4, 5 and 6.

8) Obviously, the two cards that the audience got and put back at this time are spades 7 and diamonds 8. At this time, the top card and the bottom card are diamonds 7 and spades 8 respectively.

9) Hold the cards on both sides of the stack vertically with the thumb and other fingers of the right hand, and then shake this hand to throw other cards into the other hand except the top card and the bottom card.

10) Show these two cards to the audience, and he will mistakenly think that they are the two cards he drew.
