Since I now have the game, I can now update my list:
I have officially dropped Lucina as a main in favor of Chrom. I’m continuing to main F!Corrin, however. Incineroar is a bit tricky with his Alolan Whip but I’m getting the hang of it. I forgot to mention I play Bayonetta as well. Not too good yet at her, but getting there. I use Ridley if I feel like being petty, and I’m surprisingly good at King K. Rool! I’m looking forward to Pirahna Plant and Joker (even though I’m not familiar with his game).
