Since it’s completely irrelevant which Pkmn you put in gyms (because any Pkmn will be removed after it was defeated 3 times at full motivation) I will only put in regional exclusive. I’m from Europe so i have enough Mr.Mime, and I visited Canada last year so people will be glad to get Tauros in their Pokedex. Today i saw Heracross in a gym and it made my day! Still hope to see Farfetched and Corsola in a gym soon!
Yeah, that would be neat! I’ve seen gyms with “themes”, such as all eeveelutions(my personal favorite!). A regional themed gym would be cool if other players participated.
