A regular deck of cards
First you will need only a plain deck of cards and two die. The secret is... When you roll the dice the combined number on the top and bottom is 14. Show your audience that you have an ordinary deck of cards. Secretly count down 14 cards from the bottom of the deck. Write the 14th card down on a piece of paper and put it in your pocket. Then have a volunteer roll the die. Tell them "To make it harder for my prediction to come true, I will add the total of the bottom of the die with the top." It will add to 14. Then have a volunteer count down 14 cards and reveal your prediction.The effect..... You will appear to psychic abilities and will wow all your friends!
