I've found binding mummy to really help, all the extra land plays making zombies you can chump with, while binding mummy can tap down other players and leave them wide open for other people to deal with
I run all 3 the gitrog cards, skullclamp, braids arisen nightmare, forbidden idol and effects like vampiric rites to draw more. But dont forget that cards like six and cruisible of worlds are also card advantage especially if you use the right lands
