3-5 more land would be suggested.

lands to consider-Barren Moor -Forgotten Cave -Blood Crypt -Lavaclaw Reaches -Thawing Glaciers -card:Volrath's Stronghold-Miren, the Moaning Well

mana fixing-Sol Ring -card:Journeyer's Kite-Armillary Sphere -Expedition Map

vamps to add-Captivating Vampire -Butcher of Malakir -Viscera Seer -Vein Drinker -Skeletal Vampire -Nirkana Revenant

other goodies-Torrent of Souls -Wrecking Ball -Phyrexian Arena -Balthor the Defiled

Thanks for all those suggestions! I'm trying to avoid spending too much, but there are some that I'll have to look into picking up (specifically Vein Drinker ). I have a few of the others that I might put in as well.

Braid of Fire is a good mana ramp in red. Captivating Vampire and Nirkana Cutthroat are must have vampires. i also think Bloodline Keeper  ^Flip may fit well here. I dont like some of the aura's you have such as Skeletal Grimace . they dont seem to do much. Blood Tribute seems fun. also drop Adaptive Automaton for a vamp lord. usch as bloodline. i dont like Blightsteel Tor Wauki or your eldrazi. tor because it doesnt fit and the giants cause they dotn synergize

Awesome feedback, thanks! I took out Skeletal Grimace and Tor Wauki for Contagion Engine and Argentum Armor which I just picked up in a Scars fat pack yesterday. Any thoughts on putting Murder , Falkenrath Noble , or Markov Patrician in? Trying to use cards I already own if possible.

i think you should throw in vampires that do the same thing. noble seems ok but you dont really utilise it. Markov partician is meh. try to pack as amny effects within your vampires. they all need to contribute to the field. now blade of the bloodchief and argentum can combo well. i think you definitley need mroe land and drop some of your vampires. drop your quest since its useless. Sol Ring > darksteel ignot

Cards I would cut:

• Barren Moor - Slow as a land, unnecessary.
• Forgotten Cave - Slow as a land, unnecessary.
• Molten Slagheap - Slow, unnecessary.
• Piranha Marsh - Slow, unnecessary.

I would just replace those lands with basics.

You might consider adding some more kill spells.

Interesting that you're running Olivia, the queen of pinging, but no Basilisk Collar or Quietus Spike .
Other suggestions: Belbe's Portal , Brass Herald , Cover of Darkness , Urza's Incubator .

Oh, also I would include Urborg, Tomb of Yawgmoth to get the most out of your Nirkana Revenant .

Basilisk Collar and Quietus Spike are definitely considerations I have made, although I'm not sure if it is better to kill opponent creatures or steal them. Same with Cover of Darkness , but I think vampires tend to be evasive enough. Belbe's Portal and Brass Herald don't quite fit the theme. I have looked into Urborg, Tomb of Yawgmoth and I like it, but I'm not sure if I want to spend that much money on a land that doesn't help too much.
