Exactly! Plus swordfighter is currently the only mii without any full costumes.Shovel Knight is the easiest Mii Costume lol. Just give the Mii's an Updated Assist Trophy Model, add a Music Track, and we're good.
I still think a Hollow Knight costume by the end is very likely though, considering how well that game performed on the Switch.
Etna might not be for good boys and girls (then again her outfit is pretty similar to sportswear ZSS) but I could totally see a Prinny costume.I really wish they had gone with the deluxe treatment with every Mii outfit. It still feels wrong to me playing as a Mii in cosplay with the basic ones. I think Disgaea would make for a pretty solid Mii outfit. I could imagine a deluxe Laharl and Etna would look pretty good.
