Okay....Do it however you think is best.
Here is a couple of things...
1st This is not a descussion forum that is into sharing specific methods. That would be okay in a Penguins Only forum so long as the methods are specific to the performance of the effect the PO forum is set aside for.
2nd. Though it is not the same method, if presented well, it will give the same effect to your audience. Beginning and intermediate magicians get too hung up on the method. The real secret is presentation. I guarantee you that in a layman's eyes they were handed a deck, they shuffled the deck and found a card, and you determined what that card was. One of these is already available as a $5.00 download, another looks like pre-hype for an effect about to be marketed. You can decide if the $5.00 is worth it to you, whether you would rather wait for this other effect to be marketed(which may never happen), or if you can come up with your own way of doing the same effect. One way or the other this is not the place to postulate about the specific of the method.
thank you I buy the trick that you gave it to me.
I found out the way I mention yesterday is not the good way.
I can sprite the card to two part one stack with odd number the other stack is even number
if spectator pick the odd stack after she deal down the card to 14 and stop.
when she shuffle two stack together I can count the ODD card from the bottom the 14TH card.
I wish can found out the way don't need to watch how spectator shuffle the card after her put the card back and found out the card like the video.
in the video spectator pick a card and shuffle all on him back.
he doesn't watch at all.
no key card no helper
in Taiwan there are two people found out how he make it and they say is base on some way in some cards trick book long time ago but nobody release DVD.
The books are English Version but they don't tell me the books name.
