luke teaches different ways to produce the same effect, which is really good. of course luke teaches very well and shares a lot of his ideas. he uses an old, known gimmik for one version of his trick. unless you walk around with an extra deck in your pocket just for this effect ýou wont use it very often. the best thing about the dvd is the introduction of another gimmik. sadly he just teaches u how to use it for this effect and tells you he never leaves his house without it, but if you are creative enough you will find a lot of use for this cheap new gimmik.
