Those aren't the only two to question your claim, Zachie.
My problem with this plan is framing. If we do that, the mafia can simply withhold a kill and we waste a day period.
It's not entirely foolproof either, as assuming there are two mafia left, they could just send the one that's not Zachie to send the kill anyway.
It was a decent idea, but there are ways that it could go wrong. Tbh, I'm getting a little suspicious of Pendio for suggesting it. I can see a Pendio and Alit scum tram being possible.
On the other hand, his reluctance to it makes me slightly suspicious of Zachie, since he's most likely going to die tonight anyway, and it's possibly an easy way for Pendio to bluff when Zachie is in fact his scumbud.
Although there's a lot of WIFOM there so eh.
Let's do this instead.
@Zachie before the night phase, you tell us who you're going to shoot. Deku can block that person, and EMIYA can guard you. If the person you say you're gonna target is mafia, then they'll probably target you, but it won't matter because they'll be roleblocked anyway. If the person you kill is town, however, then there will potentially be two town deaths but at least you will be confirmed.
The problem, though, is that the mafia could target the same person as you, or holster, in an attempt to frame you. But what does everyone else think about this? No matter what Zachie, you'll survive if EMIYA guards you.
