So I went through all the screenshots and trailers to see what attacks I could find. Pretty much every returning character had the same attacks but I did theirs anyway. So, here's what I found out about movesets. (Note that most of them are where I believe the attack should be relying on the characters movements e.g crouching before using a down move and which direction they were moving when the move was used.)
The first three are really the only important ones and the names might be a bit strange but I'm tired and can't be bothered fixing them.
