hypothetical pokemon that people would be interested in seeing

They should add all the starter. There are so many that would be cool to have.

I would think it would be interesting if they added ogrepon where it is super overpowered but the held item slots are taken up by the hearthflame mask cornerstone mask and the wellspring mask and once you get to a certain level you can change between mask and give the hearthflame mask +attack and/or special attack wellspring mask +speed and corner stone mask +defense

Marshadow would be perfect for this game. I can see him being a pokemon who copies other pokemon's unite moves as well as a pokemon who can take over the body of a Knocked out pokemon. since of course he is a ghost type pokemon and all. in his pokedex it is said that he copies the power and capabilities of other to get much stronger than the originals he copied.
