3+1 great card routines.
1. The magician shows the audience a plastic cardholder from which he removes a deck of cards. He snaps his fingers and suddenly there are TWO decks of cards in his hands. He opens one of the decks and pulls the cards from it, which he then uses to perform further tricks.
2. The magician shows a plastic cardholder to the audience from which he removes a deck of cards. Without opening the case and removing the cards, he spreads the cards out onto the table.
3. The magician shows a red and a blue deck of cards to the audience. He asks to choose one of the cards, red or blue. He puts that color card on one side. In a click he has two decks of the other color.
