Balthor Bomb (BG Zombie)

I found the concept for this deck on a website whose link i can not find for the life of me. the basic premise of this deck is youre dumping your zombies to your graveyard while keeping say an undead warchief or vengeful dead out there. you stick balthor the defiled when you have a load of zombies in your graveyard and then set him off. noxious ghoul comes in with a bunch of zombies effectively wiping the board and eliminating anything that a red black player might gain, as well as adding a lot of counters to your vulturous zombies. basically im looking for cards that you guys feel would go good in this deck. im thnking about maybe addng maelstrom pulse (remove putrefy for it? ) or maybe nantuko husk instead of shambling shell? also looking into coat of arms and door of destinies as tribal pump for this deck. please also note that the nantuko husk, coat of arms, and door of destinies are cards im considering but are not yet in my sideboard. any suggestions greatly appreciated!
