another good thing to throw out sometimes is the airdownward punch... as long as you touch them with it. change up the timing, a lot of people try to punish WonWom while shes jumping or zipping around in the air, or when shes about to land, and u can catch even good players off guard by throwing that in there... and gives them one more thing to think about.
a lot of people jump in with a kick then go to 33, for the fast overhead/low string... but a good thing to do once you train your opponent [most good players know to look for that before you play them too] is to jump in kick them and as soon as you kick do a downward air punch, as much of the time they will be going to block low for your 33, and they'll eat a punch.
just another thing to throw out here and there. her mind games up close and in the air are why I use her, the most fun to play in Injustice.
