Congrats to the winner!
You are tempting me to buy another 12 packs. I got my Scary Mary with that first 12 pack purchase, but hadn't planned on doing another until I earn more Starbits per gig. But, I made some more money off of selling Shards, so maybe.
I've only gotten one of the instrument cards from doing the Scary Mary special mission, which I have done at least a dozen times.
