Here's my opinions about these characters
PERFECT CHOICES
1- Krystal (i'm not a Star Fox fan,but i think that Krystal deserved to be playable,Star Fox Adventures have development by Rare before it bought by Microsoft,Krystal is also kinda a Rare character,same from Diddy,K. Rool and Banjo and Kazooie)
2-Chibi-Robo (Chibi-Robo is a very good choice,he's not very popular as Mario,Zelda,Kirby and other franchises,but Chibi-Robo deserve more recognition)
3-Saki (Saki is very obscure character,and his franchise too,but also deserved more recognition and relevance,also since Sin and Pushiment was developed by Treasure (the same company of Mischief Makers),it means that Saki will be a 2nd party character)
4-Euden (well...i don't know a lot about Dragalia Lost,but i liked that GolisoPower said,the importance of Dragalia Lost looks like very interesting,and the mobile game market is been relevent on the modern times)
GREAT CHOICES
5-Cranky Kong (Cranky Kong is a good choice,the moveset fits very well of he being a legacy character,Cranky is the Donkey Kong from Arcade games,but i think he isn't a perfect choice)
6-Skull Kid (i understand of people are chosing Skull Kid as a fighter,it's a good choice of have a Zelda main villain who is not Ganondorf,and Majora's Mask on Smash Infinite Beyond is a good rep,but i prefer a Majora's Mask stage than Skull Kid as playable)
7-Midna (same from Krystal,she deserved to be playable,and i like midna,her moveset would be great,some people debate if Midna fights with or without Wolf Link,i prefer she fights same from Hyrule Warriors,and i had to choice who will be on 6th place,Midna or Skull Kid)
GOOD CHOICES
8-Paper Mario (Paper Mario is a character where i submitted,but my submission in my opinion is okay,Mario have 4 spin-offs of the franchise,and was i said,will be very good Mario,Luigi and Paper Mario reunited,but i don't want the slot have one more Mario,will be same with Link who have 3 of them)
9-Ayumi (another obscure character,Ayumi is not my personal pick,it's okay of a japan only character have mote popular on West,if Ayumi was in a official Smash game before the Switch remake it will be a good choice,and also think Retro reps are important for Smash on general)
10-Lyn (i don't know a lot about Fire Emblem,Lyn as a playable is just good,and she will be a good choice of a non-avatar protagonist,and a female character who is not a female avatar as an alternate costume)
OKAY CHOICES
11-E.M.M.I. (um...sorry,i prefer Raven Beak as playable and...i don't like mooks as playable characters)
12-Adeline & Ribbon (i like of fighters who are two characters fighting together,but Adeline and Ribbon as fighters is not my pick,i prefer more Magolor,Marx,Gooey and Dark Matter)
MEH CHOICES
13-Ray MK II (i don't know about this character,i just know he is very very obscure and that's end of it)
14-Bokoblin (
Just one word)
