Prism is a stacked deck that you can learn in only a few moments. It is very easy to use. Prism comes on a DVD which has good production and instruction.
On the DVD, Goodman shows a live performance with two spectators and explains his routine.
In Prism, you are able to name any card at any number, but with certain caveats. You may not be able to do it for two cards in a row. This system is based upon an incredibly simple algorithm and minimal memorization. Just to put it in perspective, it is probably easier to memorize the algorithm and the rote placement of a few cards than 5 spectators that you meet during your performance.
This system has some really strong points to it. First, it can be learned in minutes. Second, the deck can be spread face up or fanned for the spectators. Third, it is easy to perform without having to twist your brain during the performance. This deck could be cut several times, so long as the performer can have the final cut and place things back where they should be.
Some weak points with this stack include that you cannot actually name any card at any number, but it appears that way, at least for the first card. After the first card, you may not be able to name a second card, but you may. It depends on what the first number is compared to the second number. Sorry to be vague, but I don’t want to reveal the method.
Goodman briefly mentions that Lewis Jones had a similar stacked deck, but it is not a full credit for the idea or method.
The ad copy is somewhat misleading. It leads you to believe that you will be able to name any card once the number (the position from the top) is called out. The spectator may think that is possible, but in actuality it is not. The perception and the reality here differ. Also, to claim that there is “ZERO memorization” is also not true. Of course there is some memorization. You need to understand the rule and a very small amount of card positions. Although it is not difficult at all, it still requires some memory cells.
Goodman teaches a few routines and a two deck prediction routine which is very strong.
Like all stacked decks, this requires some set-up. You can stack this deck in about 3-5 minutes. Goodman also teaches you how to use the deck so that it can be instantly reset, even after the spectator counts down the cards.
Notwithstanding the ad copy issues, this is a very easy method that is worth learning.
