I've been noting and working out some details for Crawlspace 13. Reworking the Whacko a bit. Narrowing into a Type that will take its player into different directions.
And adding the Psychic Type. This type of character may be anyone sitting at the table with the right cards at the start of each session. That's right, if there is going to be a psychic and who is going to be it depends wholly on the cards and it changes every game.
