On another note, I'm also playing Carl, Jin, Arakune, and Hazama.
With hazama, I can't seem to bait a slow attack for a 3C CH so I play trollzama style . (Chain Spam)
Arakune, I can' think of any approach other than partybug+2C or j.5B, but when I do land my 2C, well, I can bait a counter for 5D>j.5D>6A>5D>Wheel Loop>Laser Ender. j.5Bs can only go into 5A Mash>6B>j.6D>3C for a bit of curse.
Carl, well, I suck with, but I am determined to second him.
Jin, well, I have a resettable 3.5K midscreen,
6C>2D>j.2C>j.5C>dj.2C>j.5C>j.214C
but I mostly run around shooting ice swords.
