1. My advice, notify the player that peach is cheap before you start the match.
2. Don’t crouch cancel, Ko upwards, and give you’re self space.
She may not have as much range as marth, but she has bull **** priority, and her hit boxes last longer then most of her animations. She can easily get out of combos, by di’ing into neutral air (twirling $lut)
This is why I hate her.
But you’re fox, one of the few characters that can combo the *****(well). So work those shine combos, and remain out of her range. Space you’re self with back air too; it’s quick to come out and keeps the ***** at bay.
