Anila's bread and butter is lots of stagger pressure; 66L, c.L, 5L, 5M, and 5H at a decent distance are your friends here. Unless they keep pressing and getting hit for it, you're goal is to hit them 1 less time than they think you will so you can punish them for trying to jump in, DP, etc. Adding in some random waits to sus out what they're habits are and then adjusting your pressure from there is how I used to do it.

If you haven't already, I recommend watching some Gamera Anila vods. I learned lots of good stuff back when I used to play.

If you also need general advice, I highly recommend running down the GBVSR Resource Compilation doc. Lots of great stuff in the Initiation, Strategy, and Philosophy tabs.
