@cshore0: I too like "a murmuration of starlings" -- I'd not heard "a blessing of unicorns" before but that is perfect (unless you meet a bunch of the angry and mean kind, in which case you're in trouble [unless you're a virgin, in which case you have other problems]).
I do like a "community of cores" -- and David already mentioned "a wunch of bankers" :-)
