For Primarina if she is not listening, use the reverse candies so she is at least 2 stages below level that ignores orders. Bewear if memory serves is a normal/fighting type so fairy, psychic, fighting and flying types will do major damage. Try to get Flechinder to evolve so it can become more faster when facing Bewear. Primarina can take a few of her pokemon down but then there's the electric type who will be a problem for her but I'm sure your Lycanroc will do decent damage.
Hope this helps
