What's your definition of cheap...
if it's just a character that can be picked up easily and is still difficult to beat if your opponent has slightly less skill, I'd say
sheik tilt grab tilt grab tilt grab fair fair fair ect...
toon arrow smash arrow smash
wolf laser smash laser smash
meta attack safe attack safe attack safe WHOOOOORNADO
rob laser d tilt fair smash laser d tilt fair smash BAIR!!!!
pit arrow arrow arrow neutral a combo arrow wheel smash
g&w bair fishbow dair smash smash smash
if it's a character that has one or more tactics that serverely limit play on both ends and can force the pace of a match when mastered, I'd say
g&w don't approach from the ground or underneath
meta no escape
diddy run run run come back here darn it
bowser side b dead don't fight near edge
ddd chain throw flat stage, just don't play against him there
sheik really safe character
marth fair spaces well, reguardless of nerf
gannon don't edgeguard him
and finally, if it's a character that when play to perfection (up to todays current skill level) simply limits you so much that when you play against them, you feel cheated and discouraged to fight again (you feel counter picked), I'd say
meta once off the floor, you never touch it again
snake when you finally catch up to him, you just get smacked away, or dead
pit he's just too safe, you can gimp him, but you gotta hit him first
g&w new marth
sheik get zoned to death
rob keep away game from the gods, he also has a spike and a fly
marth not the marth we used to know, but still the same old marth
ugh, wario... vertical kill is the new spike and wario is the master
but that's just me...
