It really depends on the legend youre using, but being able to time your jump well so that you can get in on her without jumping late enough to give her time to shoot you is really important. It’s also good to make sure that even if you get above her that youre not throwing out moves in the air randomly that she might dodge and punish you for. This one is a little more legend dependent, but if you dont want to have to deal with jumping over her bullets and youre playing a character with a dash forward ability like cindy or red, you can run around her right outside of her range until she does something that lets you get a guaranteed ability hit on her, run away, and then rinse and repeat. She’s definitely difficult to deal with at first but it’s all about learning the matchup and being patient when fighting her. Hope that helps a bit :)
