Next, try to deal the card the same way as you have done previously, by laying the cards in groups of three with seven cards each. Now ask the volunteer from which group the chosen cards can be found. Once the chosen group is given, carefully collect each group of cards with the chosen group still sandwiched from the other two. Once the process has been done three times, you are now ready to choose the volunteer's card.
Now hold the cards face down in your hand. Try to ask the volunteer if he or she has heard about the word ABRACADABRA. Tell the audience that it is a magic word that will help you find the volunteer's card. As you deal the cards one by one, do so by spelling the word ABRACADABRA as each card is being dealt. Once you have reached the last "A" stop for a moment and turn the card face up. That card would be the volunteer's chosen card. Doing the process perfectly would always get you the chosen card along with knowing how to spell ABRACADABRA correctly.
Simple Card Trick
Here is a simple card trick that would not require anything to remember or practice. It is simply a matter of natural probability used for amazing effects with cards. This trick can make use of any ordinary 52-card deck. What you want to tell your audience is that you can have them choose two numbers from one to ten and then you'll try to have them show up in the deck either together or with a card separating them.
When a volunteer has chosen two numbers from one to ten, try to deal the cards one after the other face up. Surely enough you will find them surprisingly either together or with just one card separating them from one another. It can have a baffling effect on the audience, but it is a trick that is made possible by pure probability.
