It is a design element rather specific to the curators of cubes. Put simply there is a inbuilt tension on dual lands and fixing. You want fixing effects so that games are more consistent but they take up valuable cube space. By adding more dual lands your mana bases get better and less games are decided by colour screw which is great. However you als

Secondly there are just more dead cards floating around in packs.
