I am of the opinion that 1000 dec / 1$ packs have more chance of being bought by starting players. Moreover, I truly believe that including a small (and I mean really small) chance of something more than only commons and rares will make them much more desirable, not only for starting players but also perfect for the rest of the non-whales who like a gamble.
