I think that it goes without saying that vampires are one of my favorite types, so I would do my up-most best to aid you in your endeavor. Now the dilemma with any great army is that numbers are not the only factor that wins wars. Making the tokens, considering the new mechanic, will be the
simple part. Now that you are able to produce your army you must command them well. Aggro, Mid-ranged, Control. Fundamentally those are the three basic deck types that one can strive towards making. So the important question is this, do you
A) Make an aggressive vampiric army?
B) Create a token producing deck that utilizes combat tricks and spells in order to out maneuver your enemy? or
C) Control your enemy through the use of your sheer numbers and board presence and spells that directly
hinder your opponent?
These are not your only options towards building a deck but these three basic ideas should at least give you an idea as to some of the ways that you can utilize your vampiric forces.
