[SETUP] The Council

[Isis]

This is "breakable" in that you can have follow-the-cop doc onto cop and bodyguard onto tracker nights without informing the mafia who to roleblock (unless they've infiltrated the council). You would use the game thread to identify, for each player, who they should protect that night if they become a protective, making sure each person is targetted once. Then, the council grants the doctor ability to a player, then grants the cop ability to whoever that doctor pledged to target during the night.

If the mafia are in the council, they may roleblock the doctor and kill the cop or roleblock the cop and kill the doctor, but that suggests that the mafia are in the council and exposing that the mafia's most townread member may be in the council is pretty costly.

What if the council was given a random list of 3 cantidates or something, like "choose give Hectic doctor or give Isis bodyguard or give Kanna hider"

There's something unsatisfying to me about games where day 1 there can just be a Mafia Discussion thread-type theory discussion on how you order the power level of power roles. In practice games like this get run and since people have varying opinions it ends up interesting anyway, but, my aversion remains. I'd like for it to not be possible to play the "is cop the best role n1?" part of the setup before signups even begin.

6:3 with the council mechanic working like it does in OP is an overcorrection I would think.
Something with the same general style to this would be having a council that decides on a public copping N1 and N2, that'd probably be balanced.

Is each player attached to 1 protective and 1 investigative role? Also, do the roles last for just one night or the rest of the game in perpetuity?

This looks playable as is but I think there's probably room to nudge it in the direction of green EV.
I can't think of an elegant way to do that right away.
