The Scarab God legion of the undead (EDH / Commander)

This build is built around The Scarabs God`s ability To scry for X and each opponent looses X life for each zombie. So how do we do that?

Cabal Coffers, Crypt Ghast, and Magus of the Coffers will help to generate large amounts of mana to cast our go wide spells like Army of the Damned, Dark Salvation, and Empty the Pits. Ghoulcaller Gisa, Grave Titan, Liliana's Reaver, Endless Ranks of the Deadare also there to round out the Zombie creation side.

Okay we have an Army of 2/2s. Thats good but you know whats better then that? 3/3s, 4/4s, or maybe 5/5s. Bring on the lords.
Cemetery Reaper, Death Baron, Diregraf Captain, Lord of the Accursed, Lord of the Undead, Undead Warchief all pump the tokens as well as adding abilities to the zombies for some extra undead fun.

It wouldn`t be right to forget about the second ability of The Scarab God. Training grounds allows you to use the ability for cheaper while Phenax, God of Deception, Altar of the Brood, and Life's Finale help you to find some targets.

Other then going wide and hitting for lethal this deck can win through having Diregraf Captain and Vengeful Dead ping our enemies when our zombies die. Lich Lord of Unx has a similar ability as the Scarab good as it can deal damage based on the amount of zombies on the your board. And last but not least you could Gray Merchant of Asphodel assuming your devotion is up there and well this is a nearly mono black deck so it will be.
