Dead Master - Korlash EDH (Highlander)

EDH Deck Combos:

-Attack with Grave Titan, then play Darkness for two more zombies if you need more attackers but don't want Grave Titan to die from opponents blocking

-Sudden Spoiling is just amazing.

-Tormented Soul with Nightmare Lash/Lashwrithe

-Play Unbreathing Horde with Tombstone Stairwell or after Army of the Damned

-Cycle Gempalm Polluter with Tombstone Stairwell or after you've played Army of the Damned

-Use Carrion Feeder's sac ability on Butcher Ghoul, Gravecrawler or Geralf's Messenger to get an early 3/3 or 4/4

-Vengeful Dead with Tombstone Stairwell if you've got 5 or more creatures in your graveyard

-Killing Wave with Grave Pact = ensures all creatures die if you've got enough on the field

-Grave Betrayal and Call to the Grave to steal opponent's creatures.

-Army of the Damned or Tombstone Stairwell with Noxious Ghoul in play means a board wipe for all Non-Zombie creatures

-Exsanguinate with Bubbling Muck.

-Army of the Damned with Shepherd of Rot = at least 13 damage or you can use Zombie Apocalypse with Shepherd of Rot, Tombstone Stairwell becomes a beast each turn with Shepherd in play.

-Lashwrithe , Nightmare Lash on Korlash, Heir to Blackblade to double or even triple his power.

-Grimoire of the Dead with Shepherd of Rot in your graveyard is amazing. Once you've got the three study counters on Grimoire, make your opponent sweat a couple more turns if you can, cause whatever else dies will come back.

-Contamination with Unholy Grotto or Gravecawler, this will lock out any EDH decks that don't have any Black in them until they can deal with Contamination.

I'm sure there's more I'm not listing, I'll probably get around to adding more later on.
