I usually don't love tricks that involve cards, as I am not a card magician by any means, and feel a bit weird bringing out a card for one trick.
That being said, this trick SLAMS people SO hard, they won't even realize you are using a card. They are so blown away after this trick that they are almost always at a loss for words. Those who do have a vocal reaction are usually yelling or screaming because they can't believe what they just saw.
This little gem is my favorite trick at the moment, and I honestly don't see that changing any time soon. I hate telling you to buy this, because I want to be special, and can't do that if you all have it. But honestly, if you don't buy this, you are just a fool.
