This would be… a fairly large rework to Court Wizard.
I was thinking about what the Court Wizard is supposed to do, and I conclude that it’s primarily an “empowering” class; that is, it makes other people stronger, primarily by making them occ immune. The swaps are really only good for screwing over bd, so I think that should be dropped. As such, here’s my suggestion:
Court Wizard
Mimic: Choose two targets. You will use the first’s ability on the second tonight; if it’s a self-targetting ability or has a secondary target, the spell will target you instead/as well. This does not duplicate conversion effects.
Magic Shield: The target is immune to occupation tonight; occupation messages will appear to occupiers as though you didn’t cast the magic shield; your target will be alerted if you shielded them.
Basically, Mimic rewards you for identifying and communicating with your key bd members. Furthermore, if you can identify the assassin, you can kill him by mimicking his attack. If you can convince others to keep you informed of their actions, you can massively empower the bd by getting extra uses of limited abilites like window peek or wolf.
Magic shield is a modified barrier. It no longer protects from conversion, but in exchange it will alert the person you use it on when it protects them. If the person lacks occ immunity, the occupier will be told the occupy was successful (in order to avoid throwing off butler/drunk’s investigations).
