LMFAO! When I saw the thread I was like "Hey a sonic got second, wonder if he used marth" x)
Make sure you always DI it too. He gets bair as a kill move, fair as damage racker (I forget the name of the combo, but full spin dash -> fair does like 30%ish), and nair as a kill move at 200+ percent.
This one's a good/bad. You can hit him back out with whataver move or pivot grab it. Both require perfect timing though because he's still a moving hitbox. If you can always time it right and hit him back out without his jump, everything becomes 83406363 times easier on the following edgeguard. Mistiming the fair/fsmash/ftilt/pivotgrab and getting hit by the spindash makes me want to choke puppies.
I do this when sonic hits me across stage. He's charging to follow up the landing, goes all the way across stage, tipper nair eats him lol. DON'T try it when he's running towards you though. Son ic can powershield -> grab it (Espy does it on command now /sadface)
Jabbing the spin (or clanking with iSDR) is orgasmic. With consistent timing with jab punishes, the MU almost feels like a hard counter lol.
It beats it if he does an aerial afterwards. If sonic does immediate upb, you'll either eat it or hit the spring with uair. Sonic's neutral b can also beat this (since he floats a little above tipper range). Otherwise, yea, uair/bair his aerials. Getting the bair tipper is SEX.
Other things: If you get caught in fair, SDI towards him. You'll end up on the opposite side of Sonic (behind his back) and you can bair him back. It doesn't tipper but it's still a big punish.
Mash out of grabs like it's IC's. Sonic has one of the best pummels. All of this throws do 10%-12%. When Espy grabs me at kill percents, he'll do 4-6 pummels and after the throw I just ate 30-40%. Its a huge damage racker.
I'm sure most of this you already know, though lol.
