For council members - honestly there are a lot of players campaigning - Drago, Zem, TAC are the most vocal ones.
A few other options are all these players named by others:
Al
Hayumi
Ratchet
Nick
Naomi
Ultra
Me
Mango
Blue
Nana
I think that's it. Noctis is also a popular choice I believe.
It can be a double edged blade. Honestly, it looks more helpful than not tbh. Serial killers are independent scum that aren't in a team usually. There are vigilantes and more.
This game is a bigger regular mafia game with many mechanics and few additions.
