You should try levelling up your pachirisu more, he is actually very useful for this fight probably around level 15 will do. As for other pokemon options you could try catching a goldeen with lightning rod. There is a house with a fisherman and if you beat him he will allow you to fish in a pool in his house. You can also find the rod somewhere in the city from another fisherman

Where did you find the key? EDIT: Nvm found it

Where did you find the manectric mega stone?

Does anyone know how I could get EV reducing berries? I've heard that it is available in Cellia central but I can't seem to find it.

sure, pm me
