Well, for starters.
Get rid of the koala, it isn't actually a vampire.
Don't build towards Bram, it isn't that good. Tale him to 1 at most, and add another Sucker and a Knightmare Phoenix.
Lord is bad, red baron is bad, overpowering eye isn't worth it. Replace them with some generic zombie support like uni-zombie, gozuki, and mezuki.
