Zombie hybrid taking advantage of sacrificing mechanics with Blood Artist and Diregraf Captain. Adding in synergies with Birthing Pod.

Other ideas include dropping 2 cards (Maybe Metamorph, Butcher Ghoul or Blood Artist?) and adding in a 5 drop (Havengul lich/Grimgrin??) and a 6 drop (Massacre wurm)

The original idea was for a Birthing Pod/Glissa/Scroll of griselbrand package with Phyrexian Obliterator and prey upon to be included to take advantage of green. Also I wanted to use Descendent's path instead of Birthing Pod, which would have worked well with all the zombies. Not really sure which I like better, need to do some testing. Also if I ran 4 Phyrexian Obliterators (which is a creature - horror) I could have ran fume spitter, spellskite and maybe even phyrexian rager, which are all horror's.

A lot of interesting possibilities with Avacyn Restored. This final iteration just seems like a good mix of aggro and strong 3 and 4 drops that the opponent will not be happy removing or blocking due to Blood Artist/Diregraf Captain/Undying.

Looking for any criticism, thanks!
