What I meant was:
O.k. So there's a common set of about 100. Then there is a parallel set of 1/1 Auto's. So you have the CHANCE to pull an Auto of parallel of every common card in the set.
There are serial no'd sets of Game-used that you have a chance to pull as well. Judging by the amount of GU and Auto's, I wouldn't think they'd make sure you get one per pack.
However, you are guaranteed a GU or Auto per pack on average of the SP Game Used packs.
