Doesn't know how to attack
So was Applin and it got a new evolution. I get what you're saying though. I have no idea what to expect because of not being able to get Wyrdeer and Ursaluna without transferring even though their pre-evolutions are in the game and they were in a game before SV.It would be weird if it was Tropius though, Tropius is already in the game.
I agree that it's unlikely. One problem with a possible Tropius evolution is Eviolite doesn't work on Tropius right now. Making Eviolite work for a Pokemon only after a patch would be an interesting change to happen.
