My counter pick would be Arrow or the mirror, but I'll just learn the mu with Crow any advice on specific options would help a lot
Kind of like the Superman MU, 11 can stuff some options. It stuffs B12 as a match opener and if she fully holds D1-breath MB at point blank, it'll stuff it there too.
If you have a read on a crossup, dash forward. This applies in the corner and in neutral. (Generic I know, but still.) Your D2 isn't going to be an antiair so much as a corner pressure tool in this MU.
If she is sitting on full trait, you can make a read on a teleport and have plenty of time to whiff punish the laser walk with a B3. That's about the only time I would use the teleport.
Because she doesn't build much meter in neutral, you're going to be free to make reads off of MB fear wave a lot more often without getting pushblocked. Her D1 will low profile your standing 2, so either use D1 or go for a J3.
Her forward dash has ridiculous range so be ready for it and press the right button depending on the range she lands in. If point blank, D1. If in sweep range, D2. If they like to dash in and then walk back to whiff punish your options, D3.
This is just general Crow stuff really, but especially in this MU you don't want to be whiffing F1 into F13-fear wave. She has very easy options for full combo punishing trying to headbutt in. Get into F2 range and stay there long enough to make them uncomfortable, then capitalize.
In corner, D2 stuffs her wakeups and is also a free start to pressure (same as D1, tic throw or fear wave). If she delays wakeup, however, it's officially her turn. Don't press buttons. You can also use standing 3 for the same effect. The difference is if you use it right after your HKD from schizophrenia and they delay wakeup, you recover fast enough to D1 before they can. This is totally new after the patch, he didn't always have this.
Last of all be patient, but also don't give up your turn. Get in some dashes in neutral if they're playing conservative with their lasers. Make reads on their staggers, especially B2 because most won't commit and still instead B2-D1. Make both staggering and committing a lose-lose situation for them. Between that and exposing her gaps, you should be able to walk her to the corner, put fear of pressing too many buttons in her, and Oki her with mix without much fear of pushblock.
