Quite odd how 3/4 could work well on a BP team. Mawile is plenty versatile in what it can do. Can serve as a toxic staller, go offensive, be a BP booster/pivot. Sets that abuse LO and SF are my favorite. Crunch/Iron Head/Rock Slide/elemental fangs is plenty coverage IMO. Although base 50 in all but two stats isn't too great >_<
Mr. Mime is someone I'm surprised we don't see more often. Base 90 speed and 100 SpA aren't too bad. Has NP, CM and plenty of coverage so what gives? It can't take a hit to save its life but it should be a fine late game sweeper.
