There we go, that was much better.
I just can't agree that Falcon/Ganondorf have that much worse matchups. I even played some Falcon tonight against some Snake and Falco; not the best players in the world, but not random clowns. The disadvantage was obvious (I particularly hate Ganondorf against Falco) but it was always managed and there hasn't been a matchup yet that I have always lost. (Against good players, obviously.) Take a look at the Ganondorf sub-forums, especially Sliq's stuff, and you will find a metagame that is far mroe competitive than any of the bottom tier in Melee.
Yes, Mewtwo, Pichu, Kirby, Game and Watch, they all have their little gimmicks that let them sneak in a KO here and there. However, obscurity is not a good strategy. When I first got into Melee, a guy in a friendly at a tourney killed me with Kirby with some trick. I can't even recall now what it was, but the thing was, I never let it happen again. If you aren't ignorant, Mewtwo is no less a threat to space animals than something like Jiggly's u-throw to rest: Yes, it's extremely good and gives them a chance, but only if the person playign the high tier is either ignorant or "********".
Falcon and Ganondorf aren't going to set the meta-game on fire any time soon, but they have more of a core game than the low tiers in Melee did. They have great uairs still, and are decent tech chasers. If would take Falcon on Snake, probably the worst matchup in Brawl at the moment, ANY DAY over Mewtwo against Marth or Bowser against Shiek. (Heck... most characters against Shiek...)
