What if only one person gets a card of the identity suit?
In the 5% chance that only one player is dealt a card of the beginning suit which determines roles, then after this is found out at the end of the round with role reveals, that player must make a case that they were part of the winning team. If they convince 2/3 of the other players they are put on the winning side, if not then they are put on the losing team. That means, if at the end of the game the Alien won then this player has to convince other players they were the Alien. If the Civilians won, they have to convince the other players they were the Guardian.
