I had a game as Executioner earlier, and my target was a retributionist that had already rez'd by day three. I just think this is a little unfair and shouldn't be a possible exe target? Even if he didn't rez by day three, it's easy for the retri to claim they will rez someone to confirm themselves.
I also think a cleaned medium shouldn't be able to seance, just takes away the point of Janitor a little bit.
