Well it didn't go as bad as I hoped! I managed to take a stock off of each person. I played one Falco, the player's name started with a Z (he was dressed like sonic) if I remember correctly, who totally destroyed me. my second match was against a decent Pikachu, and I got gimped twice by using my jump right into his little electro balls off the stage. That was less than outstanding.
i played a bunch of friendlies though (which is what I went there for), and it was a cool experience. I feel like I went home with a better understanding of how higher level Brawl is played. i even managed to win a few matches in friendlies. A crapload against a Ganon, a Zelda/shiek, a marth ditto or two, and we played a a few low tier games, where i played as Ike, and did a good job against Ganon.
Also, Chaz was ****** when I left. One of his games looked like it was going to timeout, they were both on their last stock, and somewhere around 130 damage. He ended up getting the kill with 4-5 seconds on the clock. That was against a good Yoshi player. he also won against a good MK player right before I left as well.
EDIT: Also, big thanks to the Marths who helped me out.
