The aim of this deck is to sacrifice your zombies with Bone Splinters and have them come back stronger with Undying, or recalled to our hand with Ghoulcaller's Chant. One of the most satifying combos of this deck by far is using Undying Evil on Grave Titan, sacrificing him with Bone Splinters, removing an opponents creature and then having him return as a 7/7 and re-dropping his zombies.
Another piece is Rot Shambler, who doesn't seem like much but can get very big very quickly in such a graveyard heavy deck. Giant Growth to sneak through some more damage. We also run a full playset of Abrupt Decay, for cost effective artifact and enchantment hate.
In our sideboard I run 3 Dash Hopes, some say it's never what you need it to be, but it's so good it almost doesn't matter.
Next 3 Kitchen Finks to counter aggro decks, and yes Undying does work over Persist so with Undying evil we can bring them back a 3rd time as a 4/3 and healing us in total for 6 life.
3 Pithing Needle for their utility and shutting down combos and plays with accuracy.
3 Scavenging Ooze for some graveyard hate and lifegain, and a potentially powerful creature
And 3 Witchbane Orbs to counter graveyard hate, and anything else targeting you.
