I've been doing magic for a month now and can do most of the stuff (still working on the Braue Reversal) from Crash Course 1. Are Hoffzy Osbourne and the Click change too difficult for me? Do you have to be an advanced card manipulator to do them? Or do they just require practice and anyone could do it? I was just wondering since I heard someone else say that they've been working on Tivo 2.0 for a couple months and still can't do it. Are these like that? Or easier?
