How would you build a Tournament legal Magic the Gathering Vampire Deck?

Well first of all, pick out all the vampires you want and anything that has to do with vampires. Start out with 20-22 swamps and try to find combos within the cards. (WARNING: DO NOT USE TERRAMORPHIC EXPANSE! IT IS A WASTE OF TIME.) Once you have what you suspect to be a good vampire deck then try it out. You can always buy new cards from a local card store or from ebay if your deck does not work the way you want it to or not as well as you want it to. Black is also good for life drain cards. If you are going to make a vampire deck I reccomend you use cards like: Drana, Kalastra Bloodchief x2, Vampire Nighthawk x4, Sorin Markov x2, Liliana Vess x2 (Optional but fun) and Kalitas, Bloodchief of Ghet x2
