Poker magic, a deck of playing cards, you count a card within 10 from the top, and then count the same number of cards from the bottom to the other side.

In fact, this is also very simple to say. The key step is that the magician only needs to remember the first card. He can remember the first card (such as J of Clubs) before the performance, and then let you remember one card from the top 10 card, for example, you remember the seventh red heart 3. Then, you put the bottom seven cards on the top and give them to him. At this time, all he has to do is count the cards from the top until the card he remembers (J of clubs) appears. At this time, the number of cards counted before the card he remembers (J of clubs) is seven, and he will know that the card you remember is the seventh card.
