This is just a very simple deck made by adding easy to get cards to Necromancer Precon.
Point of the deck is to just overwhelm the opponent with the free skeletons from Necromancers ability and with cheap creatures and sacrifice spells like Detonate and Bone Spear. The few games I have played it has worked pretty well, it does run out of steam pretty early but most of the time the opponent will be at death's door or near it when he starts to get into the game and then you need one Bone Spear or Ghostfire to just deal the last bit of damage.
I usually just play the three sites I have in opening hand then use Necromancer to just draw the sites and play a site every other turn unless I have something juicy in hand that I could play if I use my turn draw for a site. 99% of the time I will be using the turn draw to draw more spells.
There is lot of room for optimization but this is very beginner friendly deck to start out with.
