This is not a Sandbox role. Setups could have 2, 3, or 4 of these in place of Villagers, and be balanced around their use. Civilian setups would change the impact of the town losing a power role. An alternative to this would be a mode which added this victory condition to the mafia regarding Villagers (and anything that might appear as a Villager)
