Yes, I tried to make a Buffy Joke.
Strat 1~ Stromkirk Captain + Stromkirk Captain +Vampire NighthawkUseful for 1v1 to 1 v 4 games, this strat will wind up making your vampire nighthawk a Flying, Deathtouch, Lifelink & firststrike. Plus it gets a plus 2, plus 2 bonus! Eat away at any monster you please, given that they do not have indestructible.
Strat 2~ Bloodline Keeper + Captivating Vampire + Stormkirk
Ideal, play Captivating vampire first. Then bring in Bloodline keeper. ON your next turn, tap to make a vampire token. It will be +2/+3 with flying. If you have a stromkirk down, they will be +4/+4 flying first strikes. Pretty big token. However it gets better. Each turn you can tap to make another token. If you manage to get 5 untapped vampires, tap them all to take control some someones biggest creature. Next turn, flip a Bloodline keeper (paying 1 black mana) and buff your creatures with his new ability. Pretty basic.
Strat 3~ All out war
As soon as possible, get a Vampire nocturnus down. Next, have an anwon ruin sage ready in your hand. Once the top card of your library is black, play your Anwon, along with any others you feel appropriate.At the beginning of your upkeep, all players sacrifice a non-vampire creature. Once they do, if the top of your library is still black, your vampires gain +2/+1 and flying. The next phase is to swing Anwon at someone who just lost some of their board state. Next, get a vampire Nighthawk and a Stromkirk Captain down. You can now swing for lethal if no one has gained life from something like Extortion.
