One single deck, three free choices of numbers and cards that match, with no apparent limitations on the spectators.
The magician shows a deck with handwritten numbers on the back that is randomly shuffled so that the faces and the numbers on the backs are mixed.
He explains a little game he plays by guessing which number a person might pick and he is absolutely sure to get the "35" from the first spectator. As a number is already announced, the spectator is allowed to name any playing card. The card is removed and shown that it indeed has the number 35 written on the back.
The procedure is repeated with a second and third spectator, but this time a playing card is named while the spectators have to choose any number. When these two cards are removed, they again perfectly match!
