I'll add a video later because this can be a bit hard to read. But if you do get it then you can in general use this in any situation as long as you can grab your, opponent.
(Starting Mist Finer: Lv.1) The beginning part up till Treasure Hunt and 5S is applicable to many characters, but the delay-on-hit coin after 5S seems to be Sol specific (in order to combo 2H after coin).
(Starting Mist Finer: Lv.1) The beginning segment may be Zato specific, as you do not have enough time to walk forward for f5S>2H to combo on other characters. But you can simply use Lv.2 Mist Finer after f5S on others.
(Starting Mist Finer: Lv.1) A few of the characters allow Johnny to loop 5S>5H>236H twice in the corner (or 5S>5H>236H followed by 5K>5H>236H due to pushback), thus you can level up to Mist Finer Lv.3 without having to use any more than 2 coins.
