How to give viewers a choice of one card, and then random card from the deck make it turn into one of the selected cards

Take the deck and ask any of the viewers to choose a card. This card you need to know, so when the viewer returns it to you, then you put a pinky on it and use the volt method so that the card is at the bottom of the deck. Then make a false shuffle in the first way, so that the card remains below. Then again do the volt and move the card to the middle of the deck. After that, you force the card to three viewers in turn, and each time make a false shuffle. Let's call this card A, this card remains in the hands of the last of the selected. Now you need to shuffle the deck really, because there is no card in the deck. After shuffling the cards, you again offer to any of the viewers to choose a card, let's call it V. Open the deck and ask to put cards into it. First, the viewer with map B should do this, and the viewer with map A should put it on top. You must transfer these cards to the top using the volt method, and then you must hide them in the palm of your hand. Then you give any viewer a shuffle deck. The viewer shuffles the deck, returns it to you, you put the hidden cards on top of the deck. Then after a little thought, you take from above as many cards as the audience chooses cards. These cards will include A and B. Next, you show these 4 cards to each of the selected cards and ask him to say if his card is among these cards, but without naming it. The audience confirms that there is a map. You put these cards in different parts of the deck, with the selected cards you put in the middle together, and then, using the volt, you transfer them to the top of the deck. Then you again offer to choose any card from the audience, let's call it C. Showing this card to the other two who selected the audience, you ask them: "Your card?". You will be told that this is another card. You change this card by the first method of changing cards to the top one. Thus, in your hand, the card A, B lies on top of the deck, and C is on the bottom of the deck. You ask without showing A: "Is this your card?". The spectator confirms that he was mistaken. Then you lightly blow on the map and say that she was his card a minute ago, and now she has turned into a map of this viewer and turns to the second viewer. This viewer says that his card. To the third viewer, you also show the map and ask him to look at the card's shirt before he confirms it. Then you say that everyone has already recognized their cards and simultaneously changing card A to B. After that, the viewer who chose card B will say that you did not show him the card. You are embarrassed and ask what kind of card he had. Get an answer and ask him to look at the card in your hands, turning it over, you confirm that this card has turned into his card. Now you need to change the card in your hand to any card of the deck and say: "Each of you saw your card, but nobody chose this card," and show the audience the card you hold in your hand.
In this and in any other focus, which is based on forcing the map, it may happen that the viewer will take another card. This point can be easily corrected. As you remember, the first card is chosen completely freely, then you should pay attention of the audience to this fact, therefore, before performing the trick, it is necessary to give the deck a shuffle to several spectators. When the card is selected, then offer the person who chooses to take another card, if he has any doubt about the freedom to choose a card. Does not matter whether your offer was accepted by the viewer or not, but your interest in any particular card will be proved. If you could not force the card for the second spectator, then leave the card in the hands of the viewer and try to force the card to the next spectator. The card that remained in the hands of the previous viewer, you must turn into a card in B, as well as in the previous description. If the card was not forced for the second time, you will replace it again with the C card. On this card, you need to finish the focus.
