Half blood super vamps is quite similar to a deck used in war 3 by Team Darkness. We called it "Adrenavamps". Quite a simple name based off the cards the deck has.
However, there are multiple flaws in the deck. For one, your damage is extremely fragile. 3/3 creatures are very weak and vulnerable to creature control. The combo is also hard to initiate. You need a minor vampire, enough quanta to adrenaline, and nightfall for optimum efficiency. To relieve the fragility that the deck has, you can insert cloaks into it. Cloaks will protect your creatures from creature control for 3 turns, besides from area of effect cards (Rain of Fire, Pandemonium, Lightning storm, Plague, etc.). You can also use dusk mantle as a shield, as the current deck is usually somewhat tight on life quanta. Thorn Carapace is also a very slow shield to bring out, since you will want to bring out your adrenavamps combo first.
Here is a sample deck based on my suggestions:
