I was combining a weak maxed prisoner with the gunner dog and it was working pretty well, but it struggles most with killing cyborg. The weak prisoner ensures he dies early and then it turns off sacred and labs. I dont think it is actually turning off the sacreds as it should, but it does turn off labs making it easier to kill the musashi/moonchild. The problem is that most have moved to using vipers or Yggs on Musashi and then he becomes harder to kill again.
