Ya I put TL on that list because I've heard that hes bad for Peach but I feel the same way you do. Everyone please post their opinions on what Peach's bad matchups are. The only ones I was able to think of in + were MK, Marth, GW, TL...mabey Luigi? I just hate fighting Luigi though so mabey its just me. Also, I heard someone say that Pika, Ganon, Falcon, and Fox were also bad matchups. Although, I completely disagree. Peach either has even matchups or advantageous matchups with those 4 except for Pika. Pika is even imo.
And ya, Peach has really good matchups.
