Not sure on how to deal with Noob other than to dash block or time your jumps...
As for Scorpion, trade ice with spear so you can get in and start up your D4 21 etc pressure. Also, keep an eye out for his teleports. If you see that it's the enhanced version coming then D4 him, if you see it's the regular... block it and 22 freeze B12 212 slide him.
I have problems with Smoke myself... I fail to see how it's an even match. Maybe I'm just playing it wrong... I could also use some advice on this one.
Smoke is a game of chess based on spacing. You have to find the distance that he can't walk backwards and then b2,3 you. Also keep in mind that clones are more of a bait tool... not something you can just throw out because you feel the need. He can teleport punch or more importantly, smoke bomb you on a reactionary read.
Good thing is that he has a larger hit box, so using all of Sub's "pressure" strings will work without fail. I strongly suggest not using a block string into clone... as that stops all momentum and is really just not good spacing. I'd rather eat a d1 then let him slip away. Just make sure you don't fall into easy patterns. Once you get smoke into the corner, the advantage is heavily in your favor. He can "smoke" out... so be ready to jump back kick to keep him locked in there.
I don't suggest jumping much unless you read a smoke bomb. Your standing 2 is much faster than any of his normals, and your d4 is faster and better for footsie, but don't whiff it... you'll eat a b2,3 and possibly a reset into death.
