Tsubaki frame data is up.
Things to know: Canceling her Lv3 attacks with a 2D puts you at 0 frame advantage on block if you cancel them on the first possible frame and don't hold D.
Moves that aren't worthy 2D canceling for frame advantage (charge canceling them actually puts you at worse frame advantage):
5A
2A
5B
2B
You can counter IDs, Jin's C/D dp and many other DP type moves and DDs on block. What's good about 6C is that it does more damage and prorates less than 5C.
There's not a single move in the frame data that only has a body attribute, and it doesn't mention any sort of invulnerability on tager's 6B either.
It does shrink his hitbox quite a bit on startup though.
