Super Smash Bros. Melee Help

i need a lot of help from anyone that plays SSBM right now!!!!!!!
i have this tournament coming up, but my gamecube broke a long time ago, so now i cant practice, and i can't forfeit or quit because the rules were that i cant chicken out

i really need strategies for using Mr. Game & Watch ( i was so pro with him, until the gamecube started to ooze this green mucus through its pores!!!)

against Dr. Mario, Young Link, Ganondorf, Roy, Pikachu, and Peach......

if you dont play as Mr. Game & Watch, could you just give me some advice for any characters in a general way????

Strange that you entered a tournament and don't know much about all the other characters.I at least know how to play with each individual characters but mainly focus on Marth and Peach.My number one stunna is Peach well usually I would telly ou is something to do wit her hover and ground attack but I believe any other SSBM expert would know whats next to do especially those entering tournaments.Well I would give a defense style play with marth but not quite easy to do.,So I will leave that out.

Lol I pwn with Jigglypuff, haven't lost a game yet :p Why use game & watch? He's like the hardest character to play with. Just keep mashing them with combos and always grab and block ;) Good luck :D
