Please rate my Yu-Gi-Oh Zombie Deck?

This is a very good zombie deck. I give it a 9/10. I would add some skull servants, lady in wights. and some king of the skull servants. They may not seem powerful together, but together they make king of the skull servants more powerful. Also I would add a vampire lord, vampire genesis, draining sheild. I would take out 1 of the call of the mummies.
