Step 1: Get a Deathrite Shaman out
Step 2: Build your graveyard and get Lotleth Troll out
Step 3: Bestow Nighthowler on Lotleth Troll and start attacking
Step 4: Just cast any spell that makes your graveyard bigger and your opponents board smaller
Deathrite Shaman - focal point of the deck being able to exile land for more mana on your turn, deal damage, or gain life.
Jarad, Golgari Lich Lord - should be beefy by the time he gets out, sacrifice bestowed night howler creature, the sacrifice night howler next turn.
Nighthowler - bestow on to almost anyone for a huge number
Whip of Erebos - whip in a Nighthowler for some nice damage and earn back life lost though the game, and Satyr Wayfinder is a sneak bring back to add more to your graveyard
Satyr Wayfinder - go get that land and add more to the graveyard
Dreg Mangler - Just because he is a solid 3 for a 3/3 haste and also scavenge. can also scavenger for 3 with Varolz, the Scar-Striped
Tenacious Dead - just for that time when you need something to keep on the battle field
Renowned Weaver - really only there for the reach
Varolz, the Scar-Striped - This card is very strong pre board
Treasured Find - to fix and damage that your mull cards do, i.e. Whip of Erebos, Nighthowler, Putrefy
Jarad's Orders - pretty much to get a nighthowler, i have bestowed one Lotleth Troll with 4 Nighthowler's before
The kill spells, because Nighthowler is even better when your enemy has more dead creatures than you do.
Grisly Salvage self explanatory... if you have a Nighthowler or Jarad, Golgari Lich Lord out on defense save grisly salvage for when they declare attackers, play salvage and hope for creatures to enter the graveyard. play this strategically
SIDE BOARD
Basically to remove your enemy's chances of beating you with board presence
