Go for it! I love the blaster boxes.
On average (pretty much guranteed) you will get 2 YGs per box :giggity:
Plus, you get at least 1 Retro card for the 10-11 set -- including a chance at a YG.
Don't the 8 count boxes come with an oversized YG box topper? If so, all the better
Go for the Hall Hat Trick in a single box -- regular YG, oversized YG and the retro YG :goal:
