Ask Kev.. hehe...
I guess it depends... for some reason, I didn't find it too hard.. but I had been playing around with VTT on my computer for a couple months, so that probably gave me a good start... try using someone else's decks at first and see how much you like it.. try it a couple of times until you can pull together a solid(ish) mix.. then decide what you really want to do.
What kind of music are you into?
