I for one got the Trilogy as a beginner in magic. Sure, I could do a double lift (though stuff in the series made mine a lot better), riffle shuffle, and simple things of that sort, but for the most part I was skill-less. Not only have my skills generally improved just from watching random things that I have added to the tricks I've invented, but naturally the tricks and flourishes themselves have been great. You will have to put in a lot of effort to manage the learning curve, but if you're willing to do that you can try this out. Overall, the disks have great value for the price compared to otherstuff on this site.
If you need any help as far as slieghts they require, which tricks ans flourishes to start with, and other little things, feel free to shoot me a pm.
