GGST - Sin Wall Break Combo
Keep the Flag Flying.
So far season 2 of Strive is pretty great. We've gotten Bridget, a winner of the popularity polls from last year, and Sin, a character I've actually wanted since release but I forgot about it because of the back-to-back disappointments in season 1. I'm glad he's here now, and also that his flag is open and flying. Not too crazy about his actual clothes, but he still looks cool.
Combo:
c.S - 5HS - 236HS.HS - 66RRC - (Walk forward) - 5HS - 623S.S - 6HS
From what I've seen of his gameplay, you usually want to use 2HS instead of 5HS. I imagine it's because he makes them airborne, so you have more combo options?
I also made this combo on the same day that I tried him out, which was 2-4 days after his release. It took me about 15 minutes including the time it took to learn his normals.
