So far Wonder Woman is my favorite character in this game. She has literally every tool you need; super fast ground dash, fast air dash, good normals and pokes (B2 and DF1), her Amazonian Smash move gets her out of the corner, her Bracelets of Submission helps her when she's being outzoned, etc. I found that you can jump over your opponent and backwards airdash and hit j1 into her BnB which can be up to 40%. It's pretty hard to block.
Her D2 is a really good anti-air. I found that after anti-airing with D2, you can do D3 and get a free set up after the sweep with cross-up 1 or 3 or you can just combo after the D2.
I'm still trying to find a way to use her sword & shield effectively though. Any ideas?
