Simple strat: Summon a bunch of 1 and 2 drop zombies, buff them with multiple lords, and swing till the enemy is dead. Have lethal damage by turn 4. I've always had an aggressive Zombie deck of some form ever since my first deck: the Black Blue Intro Pack from Dark ascension.
Eventually I'll add Lord of the Undead. I don't have him for budget reasons: my Magic budget is going towards my commander deck right now ;) Not sure which lords he'll replace. Notable that Cemetery Reaper's ability can target enemy graveyards whilst Graveyard Marshal's cannot. Your local meta will decide whether or not that's relevant.
Even though Diregraf Colossus is an amazing Zombie, it's often too slow seeing as our curve stops at 3, I'd rather swing for 2 or 3 extra fast damage by dropping a lord or a Messenger. Unbreathing Horde is another fun 3 drop, but again too slow in this deck, as despite being a zombie deck we don't intentionally fill up our graveyard.
Feel free to add Thoughtsieze or Dark Confidant, and replace Go for The Throat with Fatal Push or something like that.
I've been advised to cut the lands down to 20, but screw the rules, I have mana.
