Have you experimented with Chalice of Life / Death?

Try and trim this deck down. Some suggestions is to remove all of the artifacts except the butcher's cleaver and silver-inlaid dagger which work well with your humans. If you are looking for help with flying try bladed pinions. You can also remove the suture priest and spectral rider as they do not have any synergy with this deck, which I am guessing is solely to destroy vampires.
