I did as well. However, I came to two conclusions. First, I'll never put in enough time to compete at a tournament level. Second, and this came after several sessions with local friends, I need nothing besides basic 2D fighting game knowledge regarding movement and defense and the 'A' button to win. It was a depressing night when I started purposefully only using that button and steamrolling people.
Before I posted I had to edit it down to 420 characters. So, given what little context I was able to provide, assume that by "win" I meant only against people who aren't tournament level and when "steamrolling" I'm referring to those same people.
