I love reborn as a game and how challenging it is,even in the first gym when i went with my dartrix-espurr-munna-linoone i had to level them all up close to lvl 20 in order to beat it and that is nice but i hate how most of the pokemon we get are the "ugly" ones and the just generally rejects of the game.
So if i started a run with mudkip and then brought fennekin as my replacement for growlithe and espurr and then added rowlett as my grass and continued on with these 3 only..will it be game breaking and would i just win gym fights too easily?
