Shadar Logoth, City of Decay

Black creatures you control get +1/+1. All other creatures get -2/-2. If a creature an opponent controls were to die, exile it instead.
The evil of Shadar Logoth, Mashadar. Unseeing, unthinking, moving through the city as aimlessly as a
worm burrows through the earth. If it touches you, you will
die. Moraine Damodred
