Pyrrha has moves from Sophitia and Cassandra which is good for me since I use both characters, so if I can't find a main in this game, I can fall back on her.
Here's the notable moves that I see from the latest video:
Cassandra 3B
Cassandra 66A
Cassandra 4AA from SC3
Cassandra 22B (move also tech jumps)
Sophie 33B
Sophie 22B
Sophie AS:B
Sophie 6A
Sophie AS AA (EX follows up with a B)
Sophie 3A+B
Sophie's A grab & side grabs
I like her command grab since it would likely be unfitting for her to have Sophie's command grab. The move I am not sure about is her 8BAK. I can't tell if the input is like it was in previous games or how Cassandra's is in SC4 where it comes out of AS*S B.
I'm sure she won't play like Sophitia does because her BB doesn't look that good and no TAS B.
