any opinions?

Here's my red/black vampire deck:

I had wrestled with the idea of the exterminator. I wasn't able to convince myself that it would be handy to cast late in the game, and I didn't want to give it 3-4 slots to try and get one into play early.

I've discovered by accident that the Blood Artist/Killing Wave makes for a great combo. It creates a scenario where your opponent is losing life no matter what, and has to figure out what is worth keeping.

It looks like you've kept the deck at a great price point, which I totally respect. It wouldn't take much to bring yours back to standard format, if that's appealing to you.

yeah check out my black sac deck http://deckbox.org/sets/233143
works just awesome witch anything that dies :p i used to play it with killing wave, and its a finisher in mutliplayer.
but i tested this deck and it works very good! i can kill enough creatures of the opponents and/or make mine unblockable and it gets out of hand VERY fast, didnt even expect it to be this agro + this deck just forces your opponent to block my creatures with anything they have cuz otherwise it gets completely out of hand, for example with a curse of stalked prey, rakish heir and then attack with markov blademaster on turn 4, if they dont block him he will get 6 +1/+1 counters ;)
