Topic: Zombie Deck

My very first deck was a zombie deck centered around Soulless One, but it has since gotten lost in many moves. I would love to create a new deck based on it, however I can't remember for the life of me any of the cards besides soulless one. Do you guys have any tips on cards that would help benefit Soulless One? I mainly only want it to play casually, no tournaments or friday night magic or anything.
