I'd check with Rune first. To say what you've identified at this stage basically amounts to a sub-role claim so I'm not sure we'd be allowed to do it en masse.
Rune, what do you say?
Yeah, this counts as a mass claim.
Also, I've come to realise matchers are kind of OPd.
I'll nerf them so that if the get 0 results or 1 result it will come up with 0-1 instead of the actual number. (Otherwise they're almost seers especially if it's a mason/villager.)
And with each passing moment the mystery will become more tantalizing. Your imagination will inflame, but so will your frustration. Never knowing, only guessing, what could possibly be inside that box.
