The focus of this deck is to get out as many Gull Draz Vamps and Cullblades as possible then playing Sorin and using the -3 ability right away and attackig with all of the now much stronger vamps. Along with the pulse trackers the game should end right there. But from what ive seen, with this deck the opponent is already dead way before you need to do that so this strategy is really only going to be used if the opponent has a lot of life gain capabilities.
