If only you had the thing where it shows outcast and evil cards.
Well as long as there is no Poisoner than you could attack all Knights.
unless all three knights are evil, probably not, since the drunk disguises as a villager role not currently in play.
i feel like this is a doppelganger+shaman game with one of the knights being evil. since it also shows on the top left corner that there's 3 evils but only 2 minions, then it's also a puppeteer game, so there's most likely no poisoner/corruptions and they can start stabbing all the knights in the skull in peace :D
