Your welcome ^__^. I'm glad I can help ^__^.
It is an interesting concept, although I wouldn't advise anyone to try it. I'm not against it, though, and I think it's a pretty cool idea.
I wouldn't think he does. Wolf is a pretty well rounded character.
I wish I could tell you. It's been so long since I played him X__X. From what I remember, you should be able to. His Sheik was pretty predictable, and his Falcon did what every other Falcon did. I remember when I played his G&W, it was just like the Pit MU said. I listened to it, and it basically worked against him. But again, I can't tell if he's the same now. The last time I played him was probably last month X__X.
I think as long as you have a general knowledge on what to do against each character, you should be fine. And also, don't underestimate yourself! Saying your Wolf is bad is only going to make it worst! Think positive ^__^. Even when you're losing, don't give up! There's a chance you can still make it!
