[Update] Better Nagoriyuki round start frametrap wallbreak overdrive combo [notation in description]
Combo Notation:
fS - fSS - 214H - cS - 214H - 623H - 236K - cS - cS - cS - 6H - 632146S
The tricky parts of the combo seem to be delaying the cS after the counterhit properly, since you want the 214H to hit while they are as high as possible. The other part that I would drop was the three cS at the end. You need the right height from the first tricky part so you dont get pushed back enough, but timing the second cS so they dont fall too far can be a little tight, since fS might accidentally come out.
(if you have trouble delaying the first cS timing, you might find 5K easier to do instead)
This combo does more damage and works on more characters (all of them as far as ive seen) than the last combo I posted.
