Walk backwards and block high. Congrats, she can't do shit to you. Don't respect her double low kick, you're better off to eat 3 of those than you are to block low once and get EX Balled. Put her on auto-wakeup in training mode and practice punishing her roll and EX teleport. if you can punish the naked EX tele consistently, you can punish any of her teleport~sai / EX teleport~sai shenanigans. naked EX port is the tightest of them all to hit. Oh, and you can punish u4 > u4 with standing 2 antiair if you predict it. Otherwise watch out for her doing that high swipe attack that isnt an overhead; its a 3 hit string and lots of mileenas like to stutter it at 2. Just poke n smoke, pretty sure she can't punish you for it anyways. idk her frame data because no sane player would ever pick that character against smoke anyways
