Tsubaki vs Tager is an interesting Match-up. Tager is very slow so Tsubaki can have more charges. I saw a vid of it and it seems to be very interesting.
The problem is Tsubaki vs Ragna, Bang. I haven't played the game but my initiate approach would be to spam her with safe pressure strings and not allow her to charge. This limits her damage and she cannot do that much damage with out charges from what I see.
I am saying this because Tsubaki players will probably need to find means to deal with this problem
From the vids I saw, I feel that she needs a big or bigger knockdown move so she can charge more.
