Infernal Intervention (competive play version) use your one drop death touchers and
lightning strike to survive early
aggression, and then close out the late game with your Demons and
Nightfire Giant.
Burning Anger can also be used late game to turn your deathtouchers into machine guns that pick off the opponents best creatures or use it to turn
Nightfire Giant, Ob Nixilis, or Tormentor into sledge hammers that batter your opponent with unblockable damage. Thoughtsieze will keep you informed of what your opponent is trying to do and shape your future plays. While
sign in blood can help you dig for your finishing punches.
