I just want to say that I've hit people with Byleth's Amyr (down B) way more often than my opponents would probably like to admit, which breaks shields stupidly easy and KOs very easily too. Byleth has very good range, yes, but also some devastating attacks with Amyr.
Also, regardless of how good or bad people think Byleth is, or whether Min Min overshadows them, I've had the most fun with Byleth out of all the DLC characters, and they basically became my new main. So just remember as well, even though it's popular in the Smash community to hate on FE and Byleth, in the broader Nintendo community, Byleth's inclusion makes a lot of people happy. Every character has their fans, and people like playing as characters they like. Anyway back to Geno
