Description
The Prerelease is this weekend and immediately following will be week one at #SCGINDY
It increases the chances of making a sale
(Source) As far as it goes for The Dark boosters, they contained only 8 cards, including 6 Commons and 2 Uncommons
Being one of the first iconic cards, and an absolutely beautiful looking one at that, I'm not surprised this is demanding a pretty penny right now
