I wanted to try the deathtouch-trample combination here. I threw in hexproof to keep from getting turned around or taken out too easily. A couple mana can quickly give a huge boost, trampling, deathtouch, and forced blocking to a creature, even though a single point of damage from deathtouch will allow for a quick 1-point trample. Deathgreeters, Blood Seekers, and a Blood Artist ensure things are not fun when the opposition has creatures arrive or depart, and pretty much every other creature triggers frustration. There is nothing covering the skies, however, and I may need to get back to some reach or flyers. Initially, it was pared back so far that the average was down to 1.52, which was far too low. Now the curve has been adjusted to be a more ordinary (1)/21/11/2/2/3 (1.88 average).
