It was a neat idea, though I was curious about how effective that was in that particular case. I know that Detaining Unicorn just put me off her scent, only to realize she totally was a killer later.
In that particular game, how did the killers...kill? Did detaining Uni mean we had one less death than we would have that night? Because it definitely didn't save us from deaths entirely, with at least one more killer on the loose.
And yeah, honestly I suspect you'd have won if that die roll hadn't went as poorly as possible. I enjoy these things anyway, but Team Mafia is 5:1. Which is totally possible (especially if we all really suck at being Team Villager), but certainly raises an eyebrow at first glance.
