Aside from Rosalina, my best characters tend to have counter-attacks. I'll admit, I abuse them. Rosalina doesn't really need one given her shield/offensive weapon luma.
In that respect, maybe palutena shouldn't be at the end of my list, but she's definitely the least viable counter attacker...Hmm, I guess her poor ranking has to do with disappointment, but she is middle lower of the pack as far as how effective I am at using her.
Anyone else obsessed with greninja's shadow sneak? Given his quick movements and accesse to quick attacks and counter, with decent knock back, AND a great projectile...he has become an easy choice for a main.
