NOTE: this trick requires a UNO deck.
EFFECT: the spectator chooses a card but is not allowed to look at it.The magician then gives him the rest of the deck, and asks the spectator to shuffle it. after shuffling the deck, he gives the deck back to the magiian and looks at his card. amazingly, his card matches the card on the top of the deck!
METHOD: firstly, u need to have a card in your pocket. next, force the matching card that is found in your pocket to the spectator, but do not let him look at the card. after that, give him the deck to shuffle, and  when he is done, ask him to return it to u, and proceed on to look at his card. While he is doing so, palm the card in your pocket and place it on the top of the deck. so when he looks at his card, just show him the first card! it will match the chosen card.
