A good Rachel will NOT let you in by any means. That's going to be your biggest issue. IAD Barrier will tend to work better on her than Nu though, since Nu can anti-air combo you from a distance, and Rachel can't.
With Rachel you have pretty much 2 goals:
1) Get in and stay there. Rachel doesn't have much in the way of defensive options. She literally has nothing that can beat 5A (3x) dash 5A etc. Her only hope is to IB 2C which, if read, is horribly unsafe on block.
2) Run that bitch to the corner. Like Hakumen and Tager, you can do some insane damage on Rachel in the corner. 22BC loops wind up doing something like 7k damage.
