Could the village not use this to find players? As in they have only two thirds of players vote to use the fang on a certain turn. Then, if an elim isn't killed, they know that at least one of those 2/3 are elim, and they can narrow it down, and if they coordinate it so that only 2/3 of players try to use it, they could hard clear 2/3 of the village when it is successful. Not very likely for the village to put all the effort into doing it, but it was just something I thought of. Unless elims are able to vote for the fang to happen? If so, that would get rid of the problem.
