I was interested in using land destruction with Curse of Death's Hold and Painful Quandary. By bringing tap-to-destroy with Mole Worms, I can force the use of some lands, if I even give the time to use them. Desecration Demons keep creatures at bay, as do the Typhoid Rats. Tormented Soul may not do much damage, but with Undercity Plague, it is devastating. The deck is, as most of this type are, a bit expensive. The 11/9/3/9/6/1 curve averages 2.82 and is soft at the 3-spot.
