Same thing happened to me. Heck, the first two times, I got my least favorite stage, the top of the mountain. I don't like it because you can't grab the edge. I died twice in about twenty seconds on accident, because I forgot the special attack. Then, I killed the guy twice, knocking him to the side of the mountain while it was sliding down. Then, I lost Nana to the guppy, but lived, and let him get the smash ball on purpose, he was Fox, and he summoned a landmaster.
I went to the underside of the stage, and, as I expected, he eventually rolled off trying to get near me. We were tied 3-3, death wise, and as the timer was rolling down, I killed him.
The first match I played was the very first match of the tournament, and the other guy's controller had a stuck nun-chuk, so after I won, on the tip of Icicle Mountain and dying by fish from not being able to figure out how to air-dodge, they restated the whole thing, and it didn't count.
I played a fox next, as I described above, and pulled out a win, and then an Ike, where I went too far right on Onett and was smashed off, but came back with a win.
The last fight there was lost, as I described, because I tried to please the crowd with the Ice Climbers' nearly suicidal Final Smash with five seconds left. I don't know if I mentioned, but it was the Jungle Climber level. I got that Diddy up to 70% percent w/o getting hit, yet died at 30 or 40. The starting position on that stage are terrible, and in the reverse, I would have won, but that's not how it mattered.
Anyways, call like I said, and you may be able to get a better deal. We got to choose our character and had two minute Brawls, so that helped some.
