The magician clearly shows six cards and takes away three… but when he counts the cards again, there are still six. He takes another three cards away, but recounting them there are always six! This procedure is repeated many times, for the amusement of the audience, and each time the magician is always left with six cards.
Thanks to the gimmicks supplied this routine is completely automatic, and you will be able to take away the cards for a total of six time, always managing to immediately count six again.
The poker size cards are original Bicycle cards.
