Dual Library!
Try this variant if you're tired of not drawing enough land
to do much of anything. Players now have two libraries, one consisting
of all land cards (basic and otherwise), the other all spells. Players
draw their initial seven cards in any combination from the two libraries,
and can draw from either during their draw phase or in any combination
due to a land effect like Howling Mine or Braingeyser.
