The essential part of magic with cards, or with any ''Prop" is not flashy or dexterious handling, but to look naturally inept. The best, and often most convincing magic tricks are performed by "The Successful Bumbler".
This requires careful definition, as you may too quickly create your routine or individual performance to imply incompetence. This is a bad idea.
The most convincing magic is very quick, very visual, and is comprised of absolutely no unnatural movement. If you act like a card shark, then all you will get in response your magic is the all too common and completely obvious statement "Thats just slight of hand!"
Instead; it is best to keep flourishes to a minimum. Try not to overcut the cards in a fancy way. But do not feign complete incompetence.
You must have two, and no less, ways to cut the cards. One should be a real cut, beyond reproach and contestation. The best way to do this is to hold out you hand, palm up, set the deck face down and allow the spectator to take off half, then you lift the other half, have the spectator place his half face down on your palm, then you set your half on top. Voila! You have an indisputable cut.
The second cut should be a false cut that brings the chosen card to the top, or anyplace you want it, generally the top.
I use a three stage swing cut that I will discuss with you shortly. Sometimes I employ a swing cut to undercut which gives me the same effect, and is almost completely impervious to spectators. Too many movements, they can't believe you could keep or mark a card with such a quick natural looking cut.
You must understand, and practice again, and again, and again, injogging and false Faro Shuffling.
The technique you use must be beyond questioning. It must be quick, natural and fool proof. It will need to be smooth with no unnecessary pauses. You should run smoothly from a quick cut that brings the card to the top, right into a foolproof injog shuffle/False Faro. 1 only please, don't get excessive or carried away.
Often times you can skip the shuffle especially if you have a good audience, people who want to entertained and are not interested in spoiling the mood by making you stop to prove that their card isn't marked etc...
It's best to simply ignore them, unless they are your target spectator.
You must have 3-4 ways to allow the spectator to choose a card, at least 1-2 of them should be Forces.
You must know the Pass. You will learn it here, with some variations and notes on concealing it.
You must have 1-2 Show Stopping tricks. They must absolutely blow everyone away, and you must be able to do them without preparation. A good one is a visual productions from a Horizontal Palm, Or the Back Palm Vanish...A super cool vanish that can be done inches away from someone's face and will blow them out of the water.
Other good ones are Torn And Restored, Floating a Card etc... One of my favs, I don't know what to call it, but Blaine does something similar where he tosses the deck at the window and the card appears on the other side, good trick, but requires a partner, or you can do it alone with some beeswax :) I will let you imagine that one for a bit before I cover it.
Thats all for today kids :) Check back tomorrow, hoping to get some images/videos up one of these days.
