ye if he jumps 2H
In reload the hard thing is to beat the Hammerfall. It's not that easy as in Accent Core.
There is no 100% way to do it. It's better to block it and punish with 2K-2S-2D.
On okizeme, always use bazooka. Well timed bazooka can't be backdash-buster'd. If you don't have tension, I suggest 5p-5p-5p, it pumps the guard bar like no other and safe.
What I can suggest, do lot of lvl 3 air missiles. If you are kind of close to Potemkin, and he has to block it, you can follow up with a ground bazooka. And a LVL 3 ground bazooka means
JUMP-IN MIXUP. Turn any hit into a knockdown. Don't use your tension in combos too much, because it's not so easy to lay a mat and charge(because of slidehead).
I will upload some replays of mine later
