This deck focuses heavily on utilizing creatures in the graveyard for power.

Splinterfright and Boneyard both scale on the the amount of creatures in the graveyard, and Wreath of Geists potentially puts them at double that number. With the amount of mill behind Mulch and Grisly Salvage, Ghoultree also becomes a viable card, and can usually be played for one or two mana. An Essence Harvest or two has the potential to end the game instantly, especially when used with a Wurm/Splinterfright enchanted with Wreath of Geists.

As always, advice and suggestions are always welcome. This deck is in basic planning stages, so any help given would be fantastic.
