Might I suggest Mirror Entity ?

+1 for both flair and brutal efficiency.

YamishiTheWickedOne That's a great suggestion, I'll need to find space to test it out. Thanks!

Other things off the top of my head...

Equipment tutors, because this strategy lives and dies by skullclamp. Stoneforge Mystic , Enlightened Tutor and Open the Armory and Steelshaper's Gift come to mind.

Various lords. Take your pick. Vamps have a ton. I wanna mention Sanctum Seeker for the life drain and there was some Orc or something who had a similar effect.

Nameless Inversion . it's a creature hate spell that counts as "casting a vampire".

Obelisk of Urd . easy buff, use once you're done with clamp.

Mavren Fein, Dusk Apostle . This deck is hyper aggressive and swarms the board with attackers like nothing else in EDH. He gives you more free creatures.

Bloodcrazed Paladin as an out against boardwipes.

Yahenni. He's actually good in this format just as a hard to kill beater.

I'm sure I can come up with more ideas. I like the deck a lot.

YamishiTheWickedOne Great suggestions...I like Obelisk of Urd a ton since it will be almost always free when I cast it. I'll definitely consider them and test them out!

Love the concept! These might interest you: Metallic Mimic , Adaptive Automaton , Stromkirk Condemned , Thirsting Bloodlord , Battle Hymn (gets papa markov out on t3 or t4 assuming you played dudes on t1 and t2), Dusk , Lotus Petal

king-saproling Great suggestions, will definitely consider them. Battle Hymn seems like gas!

Other lords: Vampire Nocturnus , Bloodline Keeper  ^Flip, maybe Rakish Heir . I really wanna give special mention to Malakir Bloodwitch as a way to surprise kill people/finish games or just mass heal. There was also Champion of Dusk .

YamishiTheWickedOne: I have a lot of great cards to consider from your suggestions and all of them seems great. I'll have to test them and see how it goes. Thanks!

Sweet deck! About the infinite drain combo..I'm not sure if I get how you pull it off. I know it works with Bontu's Monument because of the cost reduction, letting you cast Oathsworn Vampire for the 1 mana you make off sac'ing it to Phyrexian Altar . Without a cost reducer, how does your combo go off? Aside from that, I got a lot of use out of Massive Raid along with the aforementioned Battle Hymn .

imSandstorm: The combo starts by having an additional vampire in play or if you have both Oathsworn Vampire and Blood Artist in hand to cast to generate the extra body to sac. How the combo works is this:

1. Sacrifice any vampire and Oathsworn Vampire to Phyrexian Altar for ( Blood Artist 's drain will trigger)

2. Cast Oathsworn Vampire from your graveyard (you can cast him now that you've gained life to enable it)

3. Edgar Markov’s ability triggers creating a vampire token

Repeat steps 1 to 3 infinite times.

D'oh! Forgot the eminence ability doesn't care where you cast it from. Sorry about that! Thanks for the explanation.

I’ve had a ton of luck with Impact Tremors and Purphoros in my Edgar Deck, especially if you repeat cast. With Purphoros out, each vampire cast will net you 4 damage to each opponent.

MannyBothans: Purphoros, God of the Forge is spicy. Would have to test it out for sure!

Enral what amazing Edgar Markov Commander Deck u have

I'll second Impact Tremors . Also Goblin Bombardment .

Since you don't run duplicate basic lands, Tainted Pact should be pretty good. Since you are already running changelings, Gravecrawler and Haakon, Stromgald Scourge can substitute Oathsworn Vampire in the combo. Check out my list: Edgar Aggro

What do you think about Cover of Darkness and Springleaf Drum ?

Also isn't 32 lands too low?

For card draw I'd also recommend Tymna the Weaver and Minions' Murmurs

Vlasiax: Both are great cards that I seem to have trouble finding the space for but will definitely put them in as I decide what to cut. Would have included Tymna if he's a vampire...I'm a sucker for staying on theme.

I'm personally not too sold on Sorin (4 cmc for +1/+0 anthem or 1/1 token? Isn't it too inefficent?) and Dusk / Dawn (3 power is quite high and might not kill combo pieces). So I'd swap these out for more draw and try to win by aristocrats.

Vlasiax: Sounds like a good change, I'll swap them out and see how it goes.

While at it - I think this deck needs Ad Nauseam . Thanks to the low mana curve you can easily draw like 20 cards at once.

Vlasiax: Not a bad idea, I will definitely try it out. Thanks!

What do you think about Pawn of Ulamog , Carrier Thrall and Zulaport Cutthroat ? I think they might help with providing bodies to sacrifice and value.

Vlasiax: I don't think they really fit in the deck as it is more of a hyper aggro rather than an aristocrats kinda deck. I'm also trying to limit my vamps to as many 1 drops as possible so the 2/3 drops need to make an immediate impact.

I actually REALLY like pawn, or Carrier Thrall especially. They're the perfect targets to fuel Skullclamp. 3 creatures for the price of 1, or 2 sacrifices and the mana to draw the second time for free. Just like Dusk Legion Zealot , he's incredible value as fuel for setting up stronger plays.
