I went into the lab tonight for a few minutes, testing stance cancels and frame advantage. Here's what I found out:
In Lasso Stance, canceling into trait: b+113, 11, and 33 are negative on block, but unpunishable outside of Superman's Super. 112 is plus quite a bit on block, somewhere around +7 or more, enough to punish a reversal Corps Charge with SS b+1. Everything else is technically punishable on block if you don't go into a special, though I bet you could get away with many of the normals. Most if not all of her strings can be block-stringed into BF3 MB or Parry to stay safe.
In Sword Stance, canceling into trait: 2, 22, 2b+1, and f+12 are negative on block, but unpunishable. 112 is seemingly plus a little on block, though I don't think it's nearly as good as LS 1124. Generally there's not much point to going into LS during her SS pressure outside of 224 xx BF2 MB IMO, but it's good to know about her options or lack thereof in this case.
The only super consistent option after blocked SS BF3 MB is another BF3 MB. BF2 MB can work but it's very hard to get a strong combo after mid-screen due to spacing. After blocked SS BF3 MB in the corner, you can follow up with d+2 and they have to block it. Hard to punish for most characters, especially if they're not ready for it at that range. Follow up with 2b+1 into full corner combo. b+2 works half the time, depends on how far you get knocked out.
In the corner, in SS, outside of the standard b+21, b+23, and f+3 mix-ups, I'm loving 2b+1 xx BF3. If it hits, you get a 52% combo on the most basic of full corner combos, meterless. If it gets blocked, you have days to confirm into BF3 MB, especially because of how late you can MB it.
Her BF2 MB is super plus on block, enough to block string a BF3.
Her dive kick DB3 MB is quite safe on block ... not positive but unpunishable. Why does the frame data lie so bad? I know it's multi-hitting but come on. Anyway, J3 xx DB3 MB should probably be used and abused, mixed up with J2 > 33.
Her SS parry is also quite safe on block.
for the Divepunch. to get the combo you have to MB it right? just making sure I got this right.
Yep.
