Dunno if people are still labbing this, managed to find those 2 combos working against SZ and Cassie. However it doesn't work with characters with weird block hitbox (Raiden, Tremor) and Mileena. Of course, those depends on the height 112 hits
b2 b2 213 112 db1 EX
b32(hold) NJP, 112 db1 EX
The concept of making the opponent bounce on ex ball after shocker works 0% against Jason (because guard stance)
Seems we need to classify a type of hitbox for each character. Because characters such as Tremor, Raiden and Shinnok can bounce on EX Ball with shocker by b2 b2 213 f12b2(hold) f12b2 db1 EX whereas SZ, females don't.
I also noticed that Mileena has a weird action on her hitbox after blocking, making her backing a little before being put on neutral. It means once she blocked the 1st ball, slightly after the 2nd one hits her. This is a blockstring leading to a full blockstring such as => 1st ball > 2nd ball > ji2. Maybe this setup can't work on her at all
Also, b2 b2 214 df2 EX b14 LRC f12b2(hold) f12b2 db1 EX seems to work on most character but not females.
It seems on female, b2 b2 214 df2 EX b14 LRC 112 db1 EX works on females, at least dvorah and cassie
(mileena excluded)
