It may seem like it can’t be done, with Mastermind and Cult Leader already having 4 abilities, but look at Alchemist with 5 abilities. I think letting Mastermind use Foresight during the day should be considered. Or, let him get feedback from Foresight instantly (bypassing prevention) and also use Convert the same night.
And something similar for Cult Leader.
Because, anything is better than RNG.
