Quote from Resarox »From thinking about it for a short time, I come to think that the main reason for doing this would be to increase consistency within archetypes that are served by the packages you create. While in and of itself not a bad idea, it collides with my personal goal that my cube is trying to achieve: Something different everytime without any form of hourlong brewing (except building the cube itself and thinking about changes almost daily :P).
Adopting package creation leads cube to more constructed-stylish outcomes. The basic idea of having packages is: "If you want one of this card, you will want all of them", which is the opposite of unexpected deck-composition that I so love about cube. I mean, I could make packages "Stoneforge Mystic, Umezawas Jitte, Recruiter of the Guard", or "Crucible of World, Life from the Loam, Ramunap Excavator", and while I'm sure I would extremely enjoy those packages, I would end up playing a smaller variety of decks over the long run, because I either assemble all the pieces or none. This last part is hinting at the more constructed-style gameplay you'll get. You either have Deck A because you managed to get package A, or you have Deck B because you got package B and so on.
I'm sketching it in a binary way and I know it's exaggerated, but without very in-depth analysis of the idea I wouldn't know where to stop with the package-density and the package-composition. I know for sure however that it leads into constructed-terrain, and that is not a place I want to be at, ever.
All in all, I don't see this idea being good for me as a permanent change of my Cube-environment. It might be nice however to once in a while allow for some more streamlined drafting, if there were some packages and every player can choose exactly one and build a very specific deck with it and the rest of the cards they drafted.
