Rotting Giant

Creature — Zombie Giant

Whenever Rotting Giant attacks or blocks, sacrifice it unless you remove a card in your graveyard from the game.

Death Baron can replace at least 2x Deadly Allure. And if you want a second wining condition you could go more aggro. Zombie Infestation, for example, is a good option since it doesn't need to tap land to activate its abilities, and it also triggers madness more easily (or other graveyard related abilities). And following the aggro strategies you can use Rotting Giant if you want, but I believe it would require different sorts of lands like Evolving Wilds.

Also, two cards I believe that can match the art of your deck are Strength of Night (can give +3/+3 to all zombies) and Silumgar Scavenger which may help you to attack later on.
