I dunno, I think different teams work well in different games. I mean judging from the people I have played with as scum(I think thats the best way to get a feel for how someone is as scum. Robz, Galz, eevee, and shraeye are all amazing scum players. I think 3 player scum teams are also a huuuuuuuuge difference than 2 player scum teams. I have lost 2 games as scum, and they were 2 of the 3 2-person scum team games I have played. I have never lost a 3 person scum team game. Largely because of the people I mentioned above. I have never been scum with yuma, or ashersky who I am sure are fantastic. Ha just checked the leaderboard and myself, shraeye, and galz is the best %.
All that aside, I think the mafia team needs to look at the current town they are against. Their are people who are very dangerous to other people. I think a me, robz, ash team would be great unless galz or twisted archer were alive too long. I think an eevee, yuma, ash team would be great unless voltaire or liopoil were on the town too long.
