Not really. =(
Anyway, I've been going heavy on Squirtle, so I have some more things to say.
I've cut down on the shell-shifting again. Basically the only way I can explain this is that the more you use it, the more your opponent will get used to it. If you want to spam some form of fake-movement, spam empty short-hops. Why? Opponents are more used to empty short-hops, seeing as it's universal.
As far as shellshifting is concerned, the more variations of this that you can preform, the better. Fox-troting out of this is useful, as well as jumping out of it for increased momentum. Actually, spam that jump, too. It makes it way easier to land behind your opponent when you attack with an aerial. Aim for this everytime.
I sometimes attack slightly higher than my opponent, and then fast-fall into them. Since most of Squirtle's aerials are sex kicks, this works well. The knockback is minimal, so attack again immedietly.
Never attack a grounded opponent with an aerial unless you have a jump remaining. Back off if you don't.
