Hello to fellow Smoke players, I'm new around this site and thought a good first post would be to share some combos.
I've been using:
3,d1,2 Smokeball, 3,d1,2, 3,d1,2, d2. It does roughly 38% i think.
b2,3, Smokeball, (nj1,) 3,d1,2, 3,d1,2, d2. It does 36% without the nj1, I don't remember atm if that puts the gravity too high to get uppercut at the end.
For quick punishes like Reptiles dash I've been using 2,1, Smokeball, nj1, 3,d1,2 3,d1,2, d2. Mid 30's
In the corner you get the juice combo, 2,1,4, Smokeball, 3,d1,2, 3,d1,2, d2. If you lead in with a jump punch (not neutral) it does 42%.
After 3,d1,2 I usually dash before I throw the smokeball, it sets up the timing really nicely. You can mix up the end of the combo and not do the uppercut to get better oki, it doesn't sac too much damage. Also you want to do the quick uppercut with simultaneous d+2 presses to get it on the end of these.
All of these are kind of basic, but they are reliable for me, and flexible enough that if I miss something I can usually make up for it. Hope it helps someone here, and I look forward to future conversations about everyone's favorite dork. Seriously, his intro quote is so dumb, there is definitely no fire anywhere in his moveset.
