VAMP.a

Thanks for the tips!

Not so sure on "vampire nocturnus"... with the affinity this has to black, maybe if this was a mono black vamp deck then deffo! I agree on the "Stromkirk captain" front and the "vampire nighthawk" and the lands!

1 Nocturnus combined with some Scry effects can be rather deadly, even in a B/R deck.
If you want to play with many counters you could take a look at "Bloodlord of Vaasgoth" ({3}{B}{B}; 3/3; flying; Bloodthirst 3 (If an opponent was dealt damage this turn, this creature enters the battlefield with three +1/+1 counters on it.); Whenever you cast a Vampire creature spell, it gains bloodthirst 3.)

already have stromkirk noble

The Gatekeeper is amazing, but rather unsoppurtable in a B/R deck with tripple {B} in it's costs.

d4rkcell - I didn´t saw him, sorry. It was only some advice based on my own vamp deck and experiences to play with it.

Muktol - yep, thats true. But depends on mana base :-) In my B/R vamp deck gatekeeper works very nice :-)

I think I should perhaps take out the 2 curse of stalked prey and replace with something like Quag Vampires or Viscera Seer, What do you think?

Quag Vampire is not bad, but you need some cards, which you can put on the table in first turn. 2 aditional mana for kick is too much and you have better creatures for 3 mana (nighthawk, captain...). For Viscera Seer you must sacrifice creature. Which creature you want to sacrifice ? All creatures you have, are better than this ability and it will be wasting to sacrafice these creatures.

Pulse tracker, Guul Draz Vampire will be better choice.
And try to think of blade of bloodchief, for each dead creature on the table, you have +2/+2

The Problem I see with "Guul Draz Vampire" is that they are a 1/1 for 1...and nothing more, untill you allready are on the way of winning the game. Personally I use "Guul Draz Assassin", but only as "Lighning Bolt" No3 and 4.
As for removing "Curse of stalked Prey", I would decide either to use the curse or "Rakish Heir", each has it advantages. The curse is harder to remove, the Heir gives you an additional blocker. But 4 cards with this effect should be enough.
If you want to try one of the 2 cards, I would give "Viscera Seer" a try. When your opponent wants to destroy one of your creatures, you can always sacrfice it and scry 1...better than loose a creature and do nothing.
I would do some testgames to see what works for you, and what doesn't. Always the easiest (and most of the time the funniest) way to get a deck right :)
Oh, and you could add some deck tags to your deck, so that others might find this one more easy.

I am going to playtest a few changes i think. I see Quag vampires as a good card merely for its swampwalk ability and its 1B, the added bonus is the multikicker if i get it in the late game it can be better and the counters work well with the concept of the deck which is to beef up them vamps with plenty counters! Might be more of a sideboard card though. The Viscera seer i see me using it to block and then sac it to scry. If nothing else it protects me and gives me the scry. For me a one drop creature is never going to be better than Hedron Crab in blue mill or stromkirk noble in this type of deck. Unless someone out there knows something i dont?

More cc1 spells enable you to make sure you can play something in T1, and/ or T2. From that point of view its quite important to have a good mana-curve, otherwise your opponent could overrun you, while you still wait for your mana. But the cards shoudln't be total useless if you draw one of them later on. So the two primal question you should ask yourself if you have a cc1 card infront of you are: "Does it fit and support my strategy" and "Does it have any use if I draw it e.g. T5" if you can answer both questions with yes, its worth taking a look at that card.
Hope I got the right answer to your question. ;)
