Yo I just practiced some 6c corner punishes today.
6c dash cl.5c nj.b nj.c j.2c land cl.5c 6c 214 b is easy and works for every char.
6c 66b link cl.5c nj.b nj.c land jump again j.2c land cl.5c 6c 214 b. This one is a bit harder but still works on everyone.
6c dash cl.5c nj.b nj.c j.2c land cl.5c delay 2b 236a 6c 214b . This and next dont work vs Linnie
max range 6c 236a 5b 236a nj.c j.2c land 5c delay 2b 236a far.5c jump forward j.b j.c j.a land 5b 6c 214 b. This one is pretty swag and hardcore. Its kinda easy to confirm after blocking some shoryu moves what pushback a bit or after whiffed walds charge move. Every tatsu can be replaced with Kamikaze (41236 D) exept last combo(u should do it after last 5b)
If u stuck with some parts of combos feel free to ask. Good,luck with Akatsuki practice.
