What pokemon would go best with espeon and blaziken? I was thinking maybe a walrein or somthing.

Just pick a Pokemon you like. It all balances out with stat increasing items. If you want to make it like a normal team then you probably want water like Walrein, or some grass or electric Pokemon.

Well, since there aren't stat difference, any water type would be fine.
