Not sure what you're going for, here. All packs have all cards; some packs have featured certain traits, which meant the odds on certain guys were higher. For instance, in the "Catch Me If You Can" pack, you were guaranteed to get three cards out of a specific pool of players with a high Speed rating. Additionally, the chances of getting golds and diamonds were doubled for those packs, with those odds being applied both to the 3 cards in the Speed pool, and to the 3 cards in the general pool. As well, there were flashbacks (featuring speedsters?) added to the game and those packs were the first place you could get them (and at a higher rate than they have been available since).
With the packs this weekend, in addition to new flashbacks, instead of a featured stat, the packs were listed as "highest rate of golds and diamonds". Unspecified, but presumably more than 2x, since there was no featured stat with the packs. This is consistent with the apparent influx of value cards, temporarily depressing card values on the market, nearly across the board.
Now, last week (IIRC) there were no flashbacks added and the packs had the same "highest rate of golds and diamonds" language added, and we didn't see the same effect on the market. Maybe the "highest rate" wasn't tweaked high enough, or maybe people bought fewer packs because there were no flashbacks.
It seems to me, there are 3 features SDS builds into these packs: higher-than-double drop rates; flashbacks; featured stats, and SDS chooses two of those features per pack type.
