Okay I played a really really good Litchi player today. It's a very even match up. You just want to play it very safe (no random ice cars). The more risky thing to do is 2D but it works well if the Litchi is playing her poke game. Make sure you know she is not going to dash over or past it though, or you'll lose most of your health lol. She will look for your mistakes and punish you hard. I did good rounds on her by keeping pressure on her and mixing it up. You wanna capitalize on her wake up and predict well which way she will roll or how she will get up. When you have momentum on Litchi it goes your way pretty well. That's all I can say for now, hope it helps.
