I made an updated list
The only ones I'd say are 100% set in stone are: Dragonite (My favorite), Gengar, Breloom, Gardevoir, and Dracovish, for one reason or another. The first 4 are just because I really like those and no other Pokemon from those types can compare, and Dracovish is set in stone cause it's funny in competitive and I don't like most Water types.
The ones that are
most subject to change are definitely Snorlax, Garchomp, Lycanroc-D, and Typhlosion. The only reason Typhlosion is subject to change is just because my opinion changes a ton, even if I like it a lot. The others are also ones I like but can definitely be overshadowed by another Pokemon in the future due to their, atleast to my picky ass, flaws.
What are some Pokemon I could see appearing on this list in the future? The only one that barely misses the list here would be Hippowdon for favorite Ground. I really like Hippowdon, and hippos are cool, but Garchomp just barely makes it here over it because it has a little more coolness factor. Other ones could be Drampa for Normal, Tyranitar for Rock, and Talonflame for Fire.
You should expect this list to change within the next 24
