Actually, the vampires are in a lot of movies, books, serials and now Wizard of the Coast have created a low cost black creatures arround them. I´ve bought the cards in internet and my deck is something like that:

2x Guul Draz Vampire
4x Vampire Nighthawk
4x Gatekeeper of Malakir
4x Vampire Lacerator
2x Child of Night
4x Blood Seeker
4x Disfigure
4x Sign in Blood
4x Tendrils of Corruption
4x Vampire´s Bite
4x Vampiric Link
20x Swamp
It´s a 8 Euros deck. No rares, only vampires.
