Hi! I am making a zombie necro for a friendly neighbourhood Magewars contest and I am looking for feedback and ideas, so please comment.

The main idea is to make a zombie horde of 4-6 (preferably including shaggoth-zora) swarm enemy and pin him to the ground with tanglevine and the like. If he survives he is to be killed off through poison.
Malacoda+Grey Wraith should act as guardians if/when needed.
Wand is to be used as counter if either book or staff is dispelled.
