LIQUID bro...
you're mindlessly using counter.
First step is to never use counter again, until you're better at everything else.
Counter isn't a combo breaker, it is an anti-aggressive read or reactionary tool. Countering well above someone (where it won't hit anyone) after being up tilted 5 times won't do much
Actually, lol, i can't believe it, you made this Dr Mario hate his life just by countering in neutral over and over again at some point. I guess he really didn't understand why it wasn't working for you before and got desperate after the first 3-5 times you threw out really really bad counters that he just ran into.
He completely forgot about pills, grabbing, or shielding.
