I only play melee. My main is Ganon and I usually get to the semi-finals in tournaments. My only real problem is Sheik, though I can handle that matchup pretty well now too. Still a bit of a pain though. Falco is also pretty bad, but I've beaten Falcos that are much higher ranked than I am myself on a few occations. I'm surprisingly good at killing Foxes actually, unless they are way above my level.

My secondaries are probably Marth and Falco I guess, though I usually just stick to Ganon no matter what in tournaments. I can also play most of the low to mid-tiers pretty well, and can do quite well with my DK or even my Pichu in low-tier tournaments.
