If you have just started in flourishing/cardistry, then no, The System is not a good resource in starting out. The System contains a lot of complex two handed cuts and one handed cuts that definitely require your basics. Furthermore, The System does not really teach the flourishes well, it's just a slow mo of the flourishes. However , IMO I think that The System is a essential DVD for a intermediate flourisher.
If you've just started, you can refer the the hundreds of forum posts on the internet. Many of them would recommend Genesis v1 by Andrei Jikh or Xtreme Beginnerz 1 by the Handlordz group. However, I feel that you can also refer to the thousands of videos on YouTube teaching the basics such as the Charlier Cut, The Spring etc.
If you're an intermediate flourisher, I would recommend picking up The System. Hope this has helped!
