We should probably compile a list (since the S.Lab board doesn't seem to have one) of S.Lab's common oki/unblockable set-ups and how to escape them.
j.214A knockdown > Command grab/jA set-up: You can backdash and the set-up will whiff and you should be able to 5A S.Lab out of the air.
j.214A knockdown > Command grab/dash 5A set-up: This only seems to be used to beat out backdash on wake-up. This one gives me more trouble than the other one. It is hard for me to tell which one is going to hit first. Honestly not quite sure the best way out of this one. If you jump, her 5A should hit you. If you DP, her 5A would hit your autoguard and then she could go into her DP. If you block or roll, her command grab could hit you first. Gear super would work fine though
knockdown/blockstring > Buffalo Hammer (low) and 214A/B (high): It's unblockable. You can DP her 214A/B. I would guess that you could roll as well assuming it isn't meaty but I never tried that. Gear super also works against this one.
Those are the ones I remember off the top of my head. She has a crap load of different set-ups and if anyone has any others (and ways to escape them), please share them.
