have you been to the trainer tower? if you have that is ok, but if you havent, that is not good. because the trainer tower you need to make sure all your pokémon is the same level as your highest-level pokémon. because if you bring for example 5 level 50 Pokémon and 1 level 70 pokémon means that you'll fight all level 70 Pokémon in the trainer tower.
hope all this information helps.
