Mike, bummer on your break. Make sure you check for the suit card variants and french. I am guessing you probably already did. Also, they did variants on the canvas in red and black as well. I think the GU are now one in every 4 boxes or so this year, so I would not expect to hit many of those at least based on what I have seen in breaks. Funny they are now harder to hit, but not much better in value than when they were one per box. LOL
I haven't bought any hobby boxes, but have been in on some 4 pack breaks and thought I did OK, but not great.
Hope your luck changes with the blasters.
