DESCRIPTION
Almost every land d. card also serves a secondary function (detritivore, shivan wumpus, avalanche riders for beatdown...acid-moss for mana accel.) it makes it hard for any deck, and i do mean any deck to catch up once you take out their first three lands and then lay down a shivan wumpus.
gemstone cavern, first turn on the draw is awesome with boom bust! The SB is totally against U control (I know, there is more out there than U control, but I don't see it)
