I noticed that about black cards too. The two black Into Packs (or Decks, if you prefer) from Zendikar and Worldwake make Vampire decks way too strong. I bought the Unstable Terrain Intro Pack from Zendikar (blue/green), and it worked okay, but totally sucked against Vampire decks (even after modifying it quite a bit).
Although my mono white could probably last a good bit against it. Pro black creatures and Instants that exile target black or red creature from the game.
