Ever since I started playing MTG I've been collecting across all the sets and blocks, so I've got a pretty good inventory as far as deck types go. Vampires are aggressive and I can see them making some waves in this block. Either B/R or Mardu by splashing the W/B vampires from the recent BFZ set (such as
cliffhaven vampire or
drana's emissary). It really just depends on the meta, kinda like a pecking order; The strongest deck sets the tone for what the other people's decks construct AGAINST, but it does not define their playing style.
Also to address Drunk Cynic; Yes I do believe that there is a difference between Strategy and Personality. For example, my first Rakdos deck I ever built had the PERSONALITY of a destroy everything burn everything in sight. Its unleash mechanic just spelled out AGGRO. However, when I re-designed the deck I gave it a more mid-ranged feel to it. Instead of focusing on the unleash to attack I mostly DIDN'T use the effect. Reason being is that as aggro as I like to be I actually like my life more than the thrill of combat. Instead of pumping up a
hellhole flailer to attack i'll make his strength incredibly high by playing
titan's strength and
auger spree to boosts his attack power. Then later on I'll just play
morgue burst and bring it back to my hand AND
deal damage. So you see there are differences between the strategy behind a deck and the personality that is associated with it.
