ok wassup dude......mario is the appitamy of what smash really is.....mario is basically like a janitor....he has no counters and he counters no one he remains the same......the pros about mario...
he is....
+he is a combo addict
+his gimping abilitys are amazing
+he is not to light and not to heavy so staying alive is ok
+projectile fireballs
+cape
+and amazing side taunt were he takes of his hat and bows to the crowd XD.....
cons
-mario's recovery isn't that great leaving him gimpable
-he can be chaingrab/infinited T_T
-there are possible matchups but most of the time they are not on his side
-can die at early percentages.
you hafe to play it out as if every stock is your last...mindgame is a big key....and SH'Bairs are amazing......
FLUDD-ike,kirby,marth,toon link,gannon,etc are more easy to fludd then others....
in conclusion have fun playing mario and your reslutls will skyrocket...trust me....
