If its the throw, remember you only get 2 loops.
It also depends on the character. Take a look at the character size thread for how many loops you can get on each. You have to use different combos for different characters.
Also, remember you can buffer things ahead of time (Namely 236BB)
These are the main combos I use:
3C, D~6, (J.C, D~6) x3, J.A, J.C, 8D, IAD, J.C, 236BBBB on Ragna, Arakune, Bang, Tager,
Hakumen, Litchi, and Nu.
3C, D~6, J.C, 236B, 2D~B, 5C, 2D~8, (J.C, 9D~9) x 2, 236BB, 236BBBB on the rest of the cast. (Except Carl -_-
4B+C, 236BB, 2D~9, (J.C, 9D~9) x 2, 236BB, 236BBBB on everyone but Carl again.
Taunt combos:
For the great wakes I almost always use:
(Starter here) 6A, 2D~B, Taunt, 214D, 2D~B, 5C, 2D~9, J.C, 9D~9, 236BB, J.C, 9D~9, 236BBBB.
If I'm struggling to close the gap to land 3C combos on the smaller characters I resort to starter's into 236A x N, into D~(B or A) mixups. 9D~B, J.C is also a really handy cross-up.
