This deck is based around Boneyard Wurm and Splinterfright with Wreath of Geists attached to them. This deck has a few low level monsters, meant for sacrificing, and some cards like mulch to help you sacrifice them faster. The more you sacrifice, the stronger those above cards get. And since we're sacrificing creatures, we may as well put out some cheap Ghoultrees. With lucky hands you could have Splinterfright with all 4 Wreath of Geists attached to them for ultimate destruction. Using Gnaw to the Bone is a great way to gain life once you've sacrificed enough creatures. Don't forget they have flashback for double the life. I also added some Fogs and Clinging Mists to defend yourself while building up your creature's power.

I am fairly new to MTG and this is one of my first custom decks. I appreciate all tips, and if anybody can help me create a sideboard, that would be awesome. This deck was also really cheap to put together.
