Oh you're right, I should be more specific. Okay, so the cards are spread on the table facedown. I pick up the first card (farthest to the left) and show it to the spectators. I then set it down and pick up a 'different card' but then show them it is really the same. And I do this over and over until I reach the end, or I feel the illusion has taken long enough. I am able to achieve this quite easily if the entire deck is squared in my hands, as I simply bottom deal or false deal from underneath the top card, but it is very hard to do when the deck is spread out on a table. Palming is an option, but I do not want to buy a bunch of decks, as my mother hates the fact that I love card tricks. And I apologize, but I don't know what you mean by 'switching the cards' as there are many ways to switch them. Thank you!
