Just about. Flamethrower's quite a basic attack. It's not something to go nuts about. Oh, and that information about caping and FLUDDing Rock Smash was interesting. I'll use it next time.
Also, I think Squirtle's more of a problem than you guys give him credit for. His bairs and fairs can be quite a problem. I think Mario has the advantage due to him being able to juggle Squirtle with u-tilt and uair, Squirtle being easy to KO at moderate percentages due to his weight, FLUDDing to screw up his spacing for openings, and Mario being able to bair wall him like he can wall us, and Squirtle having a horrible recovery, but I think it's more 6:4 Mario since Squirtle can be a problem in the air, his agility, his strong D-smash to wait out for, and one of his throws of which I can't remember that is quite strong. That's what I think, at least.
