Ok. So I look at it this way. 4 fighters and 4 prepper/thinkers. None of the smart guys are really gonna outsmart the others that much so I only need one of them. I pick Reed.
SBP-Nobody here is beating him 1 on 1, obvious first pick.
mangog- without supernatural abilities nobody here can put him down. The only that can beat him is on his team. Nobody else is needed I'm.
I think Reed,SBP and Mangog can take this without a 4th person honestly. King Thor or Brainiac if I have to pick a 4th.
