Mario:
Best: Corneria
Worst:Fourside
Why?:Because, fireballs are his only far range attack and they don't stay in the air like luigi's
they repediately hit the ground, so they fall off easily. Really, Any course with only gaps on both
sides on the screen,but not in the middle, and dont have many walls (except Pokemon Stadium
because it shifts forms) are a goodchoice for Mario.
