Lucina Vs. Grovyle is honestly up there for me for one of my most wanted since it was first brought up. They line up really well thematically and they both will bring in some interesting scaling questions and parts of their franchises that don't get enough mainstream attention and review. I've been very excited ever since the first time it was playfully teased in a blog. Regardless of if it wins, the fact the team has shown interest I hope means they'll tackle it another time, I'd love to see their interpretations of Pokemon God Tiers, Primal Dialga, Fire Emblem Heroes Gods, the multiversal scaling, Lucina's alternate classes and forms with unique weapons.
Mystery Dungeon Music will hopefully be a big inspiration, it's an OST I love a lot and has a very unique feel, Fire Emblem's OST can have some really great battle tracks as well, I'd love to see a middle ground reached however its equally possible to get a rap track that doesn't fit and I will likely rank low
All and all, very much like the MU, hopeful for them to handle it one day.
