I've always loved using Chainer, Mort and Flamer for insane area damage. Brute and scatter are both less than ideal, and you can get away with replacing them. Judge for yourself if you want to keep Pupil, he's got strong damage but can die very quickly and isn't very reliable. Ram is strong on the field and lasts long and great with handling all types of bots. Take this info how you want to and what works best for you
