The idea is that an opponent suffers from creatures coming into play and from sacrificing creatures (Mortician Beetles). Festering March, Lilliana Vess, and Echoing Decay keep smaller creatures in line, while Kalitas and Royal Assassins keep everything else under control. Banewasp Afflictions punish for large creatures, and Vampire Hexmages make it painful to pay to pump level-up creatures. It was a deck of its times, and it did well. The 2.15 average cost was nice, coming on a stretched 13/19/4/0/2/1/1 curve that all but ensured I would have things to cast throughout and could deliver big titles by mid-game,
