I haven't played online very much at all, actually, Caterkiller. I received your PM, but I don't use my Wii to play Brawl much, so I'll have to wait to tell you mine, or you can look it up in the funhouse.
Really, I believe Smash_Brother is the best, with Armak_88 and Shecky and I all up there, as well, but not everyone participated in our tournament.
I was, indeed, making an Earthbound reference with my post above. Worth note, I could probably fight a bit better now than I did then, as I recall, though, Smash Balls, as always, were my downfall.
