So there's this game i like called One Night Ultimate Werewolf, and I am gonna tell you about my favorite combination of roles, which i like to call either the chaos version or night more version (if you don't know the game i would recommend looking it up, i would explain it myself but whenever i do that i usually end up making the other person even more confused, so you'd probably understand it more with no explanation than mine)
So in this role combo you basically make it as difficult as possible to definitively know what role you are, and so depending on how many people are playing you add some to all of these roles (with 2 werewolves by default)
Troublemaker - switches 2 other players cards without looking at them
Robber - switches their cars with another plays card (they do look at the card they took)
Drunk - switches their card with one of the 3 center cards without looking at their new card
Doppelgänger - looks at another players card and becomes that role (also the card stays that new role, meaning if for example the robber steals the doppelgänger card they have no clue what they are and whose side they're on)
if you need more roles after this, then you add one or both of these depending on the number of players
Tanner - wants to die, villagers and werewolves both lose if the tanner dies but the tanner wins if they die
Insomniac - looks at their card at the end of the night to see what they now are
if you still need more cards then you add the villager roles
So in this monstrosity of a role combo at the end of the night the only person who knows who they are is the insomniac (as long as they don't have the doppelgänger roles) and everyone else now has no idea if they are still the role they started with or if they are now on the opposite team and so most of the talking portion of the game is just figuring out what the hell happened and it's my favorite way to play
