Yeah last night I saw the one in the blitz event had better stats then the one that you sent I'm not sure where the other stats came from but from the look of it I thought it was in someone's lineup but after seeing the blitz one later on in the day I started to think the ones you sent were from a region master campaign event where the stats were nerfed a little bit compared to the real stats but too bad a 100 Simmons is coming making him a must have
Finally played the region events and sure enough that's where you saw Rose and the cards from the round of 64 elites had nerfed stats compared to the ones on the AH so that is the case with Rose so the blitz stats must be the real ones
