I created this matchup guide in my "Improvement Series" video to demonstrate the process that I use to learn matchups in Smash Ultimate. I am by no means an expert yet at Pyra and Mythra. Don't take this guide as a definitive example of the matchup, but rather as a representation of my learning process and the way I think about learning matchups in general. As I continue to learn more about this matchup I will update the guide with corrections and additions.
