Well I just go and play, the first tournament I went to, I was so nervous. However, the other players were mello and cool. There really is nothing to be nervous about, if you know anyone who will be at the tournament, just talk to them, they will not bite.
Thanks for the tips, I have a tourny on saturday and i want to do good. I always get nervous and drop all my combos and you guys know how that goes with cage ant3:
