Mafia
Spades Slick - He visits once per night, and if he comes across a juju (Die's voodoo doll, Crowbar's crowbar, Eggs's timer, or Biscuits' oven), he will remove it from the player for that night. If he encounters Scratch, he will receive a gun, which can be used to shoot a player at any point during a day phase. This gun has a 50% chance of revealing Spades.
Clubs Deuce - Everybody out of the god damn way. You got a hat full of bomb, a fist full of penis, and a head full of empty. You can smack a player to prevent them from acting at night, and the last to vote to lynch you will be killed by the bomb.
Hearts Boxcar - No idea.
Diamonds Droog - You’re very sharp and you understand the Felt abilities well enough to use them against their users. You can choose two players. Visitors to the first player (and the subsequent effects) will visit the other, and vice versa.
Village
Snowman (8) - Protects a player each night, will hook Spades instead of protecting him if she targets him. She cannot be lynched.
The Felt - They know at the beginning of the game only that they are a member of the Felt and that they can select someone to visit. (Matchsticks (11) and Quarters (14) are dead at beginning of Intermission and their abilities are difficult to implement. If necessary they could be visiting nillas.)
Itchy (1) - (Able to slow down time relative to himself, allowing him to act quickly. He also uses this to cheat often.) He can tell if a player is Midnight Crew, Felt, Doc Scratch/Lord English, or Hussie.
Doze (2) - (Able to slow down time for himself, which makes him super slow.) Bulletproof.
Trace (3) - (Can follow past trails, which unfortunately tips people off to his location in the future.) Learns who the visited player has visited.
Clover (4) - (Insane luck and lots of knowledge, will help anyone who can solve his riddles.) If he visits a Felt role, they will receive a hint about their own role. If he visits any other role, he will receive a hint himself about who he is.
Fin (5) - (Can follow future trails (dies by DD shooting at predestined holes).) He can see everyone who's visited a player of choice.
Die (6) - (Voodoo doll which takes him to timelines where different people are dead, sometimes with odd consequences.) He chooses a player each night. That player will die, but the timing is uncertain. It will happen as far back as two nights ago or as far forward as two night phases from now.
Crowbar (7) - (Crowbar negates effects of temporal objects.) If he visits Eggs or Die, any effect they’ve created is negated.
Stitch (9) - (Has effigies that he can repair or maim.) He can protect or silence a player each night. Unless it’s specified which he’s doing, the effect is randomly determined. (This could probably use reworking? I'm not sure how best to implement an either or when the member doesn't know he has the option.)
Sawbuck (10) - (When injured, sends himself and attacker or target to a random point of the current timeline.) If he is killed, he won’t die until the end of the next phase, and his attacker is hooked or silenced until then (depending on day or night).
Eggs (12) - (Can travel back in time up to an hour with egg timer, result is he can have almost limitless clones.) Not sure how to make something with this that isn't completely broken.
Biscuits (13) - (Can sit in oven waiting for timer, no time seems to pass in the oven.) His visits don’t actually do anything. If he visits Eggs, though...
Cans (15) - (Can punch people to next week.) Can punch people to the next day phase. They can’t speak until then.
Other
Doc Scratch/Lord English - He knows Spades from the start. Doc Scratch can force one player to act upon another. The acting player is not informed of his target being changed. Doc Scratch’s goal is to get Snowman killed. When Snowman dies, Lord English enters (as the same player). He kills one player each night. He wins and ends the game by killing Hussie. As either Scratch or Lord English, he can only be killed by lynching.
Andrew Hussie - You’re the author but we don’t care about that right now. You go around bapping people with brooms. For most players, this doesn’t do anything, but if you bap Doc Scratch he’ll be unable to use his ability. When Lord English enters, you change modes a bit and start hiding behind a player each night. If you hide behind Lord English or if Lord English kills the player you hide behind, you die. Only Lord English can kill you. Your goal is to survive.
