I also had him in the first version of this deck. But back then I used less creatures that I could sac and thus often had to exile him, as he was the only creature on the field when he came back with 'Undying'.

Thank you for your suggestions

I Used "Gravecrawler" earlier, but as I removed most of my other zombies from the deck I wasn't sure that I could cast him from the graveyard. I also had "Barther in Blood" in the deck earlier, but it proofed to be to expensive to play here.
I will give "Gravepackt", "Mutilate" and "Altar's Reap" a try, I was thinking about "Sign in Blood" as carddraw, but this fits better to the sacrifice theme.

Thanks for the suggestion. I will give "Howl of the Night Pack" and "Primal Bellow" a try.

I would try "Pulse Tracker" instead. Does the same damage but without the drawback in life
Oh and I would cut the "Markov Blademaster". Its a great card but too slow. It needs massive support to get through. Also you could lower the number of "Dark Impostor" to 2 or 3, his ability is rather expensive to use and thus you don't want him more than once or twice on the field.

Ups, "Sanity Grinding" is opponent only. Sorry, thought it was target player :)

Depending on your average mana costs you could try to reduce the number of lands to 20 or even 18.

Some suggestions from my own modern goblin ceck (http://www.mtgvault.com/muktol/decks/monor-tribal-goblins/)
Furystoke Giant (Finisher), Mogg War Marshal (Comes with a little friend, great to use with ETB effects), Siege-Gang Commander (Can convert goblins into damage), Spikeshot Elder (Cheaper than "Lightning Crafter" but buffed equal potent. can be used multiple times), Warren Instigator (Doublestrike, if unblocked allows you to play 2 goblins for free), Quest for the Goblin Lord (Pumps all your goblins)

I hope I was able to help

I use 12 spot- removal spells for myself, and sideboarded are 4 mass- removals. But my vampires rely heavy on damaging the opponent to get stronger...they are red vampires and want to drink blood ;)
You could also try "Gatekeeper of Malakir" a cc3 (3 black) removal on 2 legs.

I personaly like decks that can switch between mill and self mill ;)

I would try to remove "Alchemist's Apprentice" and "Civilized Scholar" as the advantage you get from those cards is to small. One chumpblock that draws you a card for cc2 and a 0/1 for cc3 that draws you one card/turn.
Remove "Cerulean Wisps" (cc1 for 1 card is Ok, but there are better spells), "Dampen Thought" (Not enough arcane spells for that), "Divination" (To expensive to play)

With the free slots I would fill up "Dream Twist", "Inaction Injunction" (Depens on your opponens, perhaps 2 more into your sideboard) and "Thought Scour"

Some more suggestions from my mono-U mill deck (http://www.mtgvault.com/muktol/decks/monou-mill/) and my U/B control deck (http://www.mtgvault.com/muktol/decks/bu-control-discard/)
Draw/Discard:
Rushing-Tide Zubera...if it dies and got more than 3 (Blocking a 4/x) )damage, you can draw 3 cards
Visions of Beyond...cc1, Draw a card. If a graveyard has twenty or more cards in it, draw three cards instead
Careful Consideration...cc4 draw 4 discard 4 or 2 (Depens if it is your turn or your opponents turn)
Compulsive Research...cc3, draw 3, discard 2 or 1 (2 cards or 1 land)

Mill:
Hedron Crab...cc1 0/2 defender that mills with landfall (3/land)
Sanity Grinding...cc3, really good in decks with high U-costs in it's cards

Defender
Kaijin of the Vanishing Touch...bounces back your opponents creatures so that he has to cast them again.

I hope I was able to help you

Your deck lacks some of the best and aggresive vampires there are. Furthermore I would remove some of the one-offs and put some other cards into your sideboard

Decide if either "Blood Seeker", "Blood Artist" or "Falkenrath Noble"... you can use one of the other in your sideboard. remove the rest
"Bloodflow Connoisseur"...remove. Cc3 for a 1/1 and you even have to sacrifice creatures to make him stronger.
"Child of Night"...remove and fill up the ranks of "Vampire Nighthawk" and "Vampire Nocturnus"
"Chosen of Markov"...remove. 4/4 seems impressive, but without any avoidance there are better creatures
"Sengir Vampire"...remove. Too expensive and you allready have enough finisher
"Vampire Interloper"...remove. There are better vampires
"Cower in Fear"...sideboard. Against mass
"Grasp of Darkness"...good card, if enough creatures die, you can think of using "Tragic Slip"
"Murder"...remove. Too expensive
"Public Execution" seems very expensive to me. The Question is, do you want to save 6 mana and so nothing in your turn if your opponent can very ofteh play arround this card?
"Trumpet Blast"...if you want to keep it, change to "Vampiric Fury". Costs 1 mana less to play, and they even get first strike
"Barter in Blood"...remove. This also hit's you and there are better spells for that if you want to
I would either focus on point removal or on discard to control my opponent, but don't try to mix it. Also BB-maana could be a problem in early games.

SOme suggestions from my own B-R Vampire deck (http://www.mtgvault.com/muktol/decks/br-tribal-vampire/)
Bloodghast (cc2, that comes again (if died) with landfall), Bloodline Keeper (cc4, produces tokens, if enough vampires are on the field -> flip -> +2/+2 for all your vampires), Pulse Tracker (cc1, does the same job as "Vampire Lacerator" but without the drawback in life), Stromkirk Captain (1+/1+ and first strike for all your vampires), Stromkirk Noble (cc1, 1/1, unblockable by humans), Rakish Heir (Does the same as "Curse of Stalked Prey" but in creature form: +1/+1 marker for every creature that does damage on your opponent)
Go for the Throat, Lightning Bolt, Terminate, Dreadbore (Good, cheap, removals)

If you want to use duallands I would recomend these:
Blackcleave Cliffs, Dragonskull Summit, Graven Cairns
Most of the time you want to overrun your opponent so "Cathedral of War" should not be that usefull. Like "Stensia Bloodhall" it just gives colorless mana. The Bloodhall would be really good if you wouln't have to tap it.

I hope I was able to help you

I would remove "Markov Blademaster", he is to expensive and comes to late. Furthermore "Doom Blade" could be exchanged against something with less target restrictions.
"Exquisite Blood" and "Sanguine Bond" may seem like good cards, but will come not earlier than turn 6+, thats if you start with 3 lands and don't draw anything other than lands. Combined with "Diabolic Tutor" that means that you have to sit still for 4 turns after you hit 4 lands and just defend.

Some suggestions from my own B/R vampire deck (http://www.mtgvault.com/muktol/decks/br-tribal-vampire/)
Bloodghast, Vampire Nocturnus, Curse of Stalked Prey, Lightning Bolt, Terminate, Dreadbore, Sign in Blood

As long as you draw enough creatures it's OK. If you start to get to many artifacts and to few creatures, it should be changed.
Those details depend heavy on your liking and can only be discovered by playing :)

I would play cheaper equipment

Some suggestions from my own kor-equipment deck (http://www.mtgvault.com/muktol/decks/monow-kor-equipment/)
Basilisk Collar (cc1+ cc2-> deathtouch+lifelink), Bone Saw (cc0+ cc1 -> +1/+0), Cranial Plating (cc2+ cc1 -> +X/+0 where X is the number of Arttifacts you control), Swiftfoot Boots (cc2+ cc1 -> hexproofe and haste. Helps to keep your beaters alive)

Kor Skyfisher (cc2, 2/3, flying), Ornithopter (cc0, 0/2 flying, artifact), Puresteel Paladin (cc2, 2/2, Metalcraft: 3+ artifacts -> Equipcosts = cc0)
Darksteel Citadel (artifact land)

Greetings
Muktol

What about "Careful Consideration", Compulsive Research" or "Wistful Thinking"
I know they have no Flashback but they give you cardadvantage and let you decide which cards to drop and which to hold.

Some suggestions from my own burn deck (http://www.mtgvault.com/muktol/decks/monor-burn/)

Creatures that are more like burnspells: Ball Lightning, Hellspark Elemental, Spark Elemental, Vexing Devil
Other spells: Seal of Fire, Magma Jet, Searing Blaze, Shard Volley

Greetings

I would remove some cards:
Boggart Harbinger (To expensive, and the card is not even in your hand but on top of your library), Frogtosser Banneret (You don't have that many expensive goblins), Goblin Sky Raider (The deck should put enough pressure on your opponent that flyers won't be a problem, if not -> Sideboard), Bloodmark Mentor (See under suggestions "Legion Loyalist"), Sign in Blood (See under suggestions "Infiltration Lens")

Furthermore I would try to make a 4/2/2 split bewteen Goblin Chieftain/ Goblin King/ Mad Auntie. Try also to raise "Krenko, Mob Boss" to 2 or 3, since he gets shot faster than you can say Lighntning Bolt

Some suggestions from my own monoR goblin deck (http://www.mtgvault.com/mutol/decks/monor-tribal-goblins/)
Infiltration Lens (Tough choice blocking that goblin, killing it and giving you 2 cards or taking the damage. Re-usable since it is a equipment)
Goblin Wardriver (Battlecry), Legion Loyalist (Battailion -> First strike and trample), Mogg War Marshal (Comes with a little friend, very good to charge "Quest for the Goblin Lord"), Warren Instigator (Doublestrike, enables you to play 2 goblins for free if unblocked), Furystoke Giant (Finisher)
If you want a tutor other than "Boggart Harbinger" try "Diabolic Tutor". One Black mana more and you get the creature on your hand.

Hope I could give you some ideas

@Jswag: Try it with constructive criticism. Or would you be happy if someone looked over a idea of yours and only said "This sucks"

When Teros comes out, the whole Innistrad Block and M13 will be rotated out, so many of your cards won't be T2 legal
Or is this deck planes as Modern deck?

Some suggestions from my own B/R Vampire deck (http://www.mtgvault.com/muktol/decks/br-tribal-vampire/)

With this manabase you will get problems playing double-red or double-black spells like e.g. "Gatekeeper of Malakir" (Tripple-black in that special case). Two possible way: either you remove all of those cards or you use more duallands: "Blackcleave Cliffs", "Dragonskull Summit", "Graven Cairns"

I would remove "Erdwal Ripper" and "Markov Blademaster". Both sound like great cards, but both come too late and need massive support to be usefull. I played the Blademaster myself and most of the time he was on the field he had to stay defensive, because my opponent hat at least a 2/2 blocker that simply would have killed him.

Try to raise the number of "Rakish Heir" and "Stromkirk Captain" to 4. An alternative to "Rakish Heir" could be "Curse of Stalked Prey" which comes earlier and is harder to remove, but you loose a blocker.

With acces to red and black I would change your removal spells to something like "Go for the Throat", "Lightning Bolt", "Terminate", "Dreadbore". I would also change from "Morbid Plunder" to something that gives me card-advantage like "Sign in Blood" or any other black or red draw spell.

Further suggestions:
Vampiric Fury, Blade of the Bloodchief, Bloodghast, Bloodline Keeper

What about "Searing Blaze" instead of "Pillar of Flame"? With Landdrop you deal 2x3dmg for 2 mana.

Muktol

Some suggestions from my own burn-deck (http://www.mtgvault.com/muktol/decks/monor-burn/)
14 Lands seems VERY few to me, I would try to raise it to 16-18
I would remove "Chandra's Phoenix" for something like "Spark Elemental" or "Hellspark Elemental". Also "Koth of the Hammer" could be removed because you want to finish you opponent until turn 4+
"Flame Slash" only does damage to creatures, try "Lava Spike" or "Rift Bolt" instead.
With some more creatures "Infernal Plunge" could also be used. Attack with your creatures, sac one in your second mainphase and play burn spells.

Some suggestions from my own infect deck (http://www.mtgvault.com/muktol/decks/monog-infect/)

I would change some numbers here if you want to play it as a aggro deck
Lower the number of "Contagion Clasp" to 3 but raise "Rancor" to 4. Also lower the number of "Phyrexian Hydra" to 3, you just need that one as finisher.

Further suggestions:
Spinebiter (Finisher), Evolution Charm (Great flexibility), Groundswell (cc1 buff with landfall -> +4/+4), Mutagenic Growth (cc0 buff +2/+2), Invigorate (best buff available to an non-modern infect deck), Might of Old Krosa (cc1 +4/+4 buff), Wild Might (cc2 possible +5/+5 buff)
