I just had some great games with Zoze, even if a lot of it was just shooting down random idea for matchup counters.
Paducah Smash: Happenin'
Edit: Random thoughts...
Zoze, your MK is starting to get smart, and I don't like it. It's so different from the d-smash spam I saw at the first Edwardsville tourney... Meanwhile, your knowledge of Kirby is starting to be really solid.
Your Marth is silly and I can punish it by rolling. Brawl Marth is a lot more about his fast aerials, since they are much safer and disjointed hitbox priority matters more in the air. Your Lucario was also kinda meh (while I'm criticizing characters), and was pretty much nothing more than smash spam and trying to time things well. High level Lucario play revolves a lot more on aerial combos. Also, jab-canceled side-Bs are nice.
I wouldn't go Pikachu for any matchup, including Fox. Maybe I'm just used to the experience of playing Stealth and Anther, but I didn't feel that threatened by it. (Even as Wolf and Falcon)
You might want to find someone with a good Wolf for practice, since that should be an easy MK matchup to get down.
For Falcon, just give up, there is no hope against a force that manly.
Uh, you did really well against my Snake. Maybe that would be different if I wasn't *obsessed* with side-B, but you were power-shielding everything perfectly... which is exactly what you have to do against snake. Just watch out for C4 more.
DDD on the other hand you seemed to struggle with. You really, really need to not let DDD grab you, even if he doesn't have a chaingrab... it's just too much damage. If he gets 20% a grab, that's more than anything you are doing to him, especially since he's DDD and you're light... it's equal to like 35% on him! Also, DDD mains will be much better than me at recovery, with well-spaced fairs and optimal use of up-B. I think you will need to look at this matchup beyond nado.
Olimar is another important matchup, but that one really comes with experience. You need to assimilate the knowledge of what Olimar wants to do with what color pikmin he has in any situation. Better Olimars than me will play directly to their optimal plays, which means high priority yellow aerials, incredible blue grabs, low percent purple KOs, and no whites flubbing up things. Don't expect to be able to pressure really good Olimar players off the stage without a huge fight; it's a defensive character to begin with, and MK is very good to play defensive against.
Diddy I really don't have an answer for... sorry my Diddy is terrible and I can't give you practice against his true banana tricks. I'd suggest MK or Kirby for now... You play Jiggs like Meta Knight, which makes it as almost as bad as me playing Meta Knight like Jigglypuff... It's probably good for my ego that we didn't play MK dittos. (All I do is shuttle loop and f-tilt) Honestly, I should learn the Diddy/Jigglypuff matchup better myself. Just send all the Diddy players my way in brackets and we're good.
Oh, and Game & Watch sucks donkey balls and is a ******** character that no one should play ever.
