Attrition is great removal utility we can sac tokens to kill other creatures, and if you happen to have both it's 2 for price of one :) I strongly recommend you to try Attrition.

Mana Echoes is so broken, if you have a creature + token, next time you cast a creature you get 3 mana for it + 4 for the token, it is crazy here.

Yeah exactly. You can use Attrition to kill most creatures, so why are you still running Pact?

Cards I consider including from the new RiX set:
Forerunner of the Legion
Legion Lieutenant
Champion of Dusk
Twilight Prophet
Elenda, the Dusk Rose

Going to swap:
Falkenrath Aristocrat for Twilight Prophet
Guul Draz Assassin for Elenda, the Dusk Rose
still looking for some space for the other 3 I've mentioned but don't know what to exclude atm. Suggestions are always welcomed.

Hey, just posted my Edgar list. I've managed to include a lot of the Ixalan cards. They were a natural fit, and really upped the power level for relatively little cash. The only card more than $5 was Twilight Prophet (well worth it.) Anyway, check out my list. I've managed to work out a nice low curve for a consistently explosive aggro start.

Happy to see you took Lil Kalki's suggestion and added Reconnaissance. I've been advocating the crap out of this card (including to kalki lol). I hope you've looked at the rulings for the card... it's hard to evaluate at face value.

Essentially (and sorry if you did your research) it allows you attack with EVERY creature you have, deal combat damage (in most instances), and have every creature untapped and ready to block.

It untaps to avoid bad blocks, and this is the face value fair use.

It untaps after first strike damage but before normal combat damage. Busted with Stromkrk Captain and a good way to get counters from Drana to your whole team.

It even untaps after normal combat damage has been dealt due to the creature still being counted as an attacking creature until the end of the end of combat stage (You untap in the middle of the end of combat stage).

Anyways, nice deck. Lots of similarities but feel free to check out my list Edgar's Dega Vampires

If I were you I would take out: Legion's Landing  ^Flip, Profane Command, Vampire Nighthawk, Shadow Alley Denizen, Mirri the Cursed, Indulgent Aristocrat, Gifted Aetherborn, Drana, Liberator of Malakir, Drana, Kalastria Bloodchief,

If I were you I would put in: Paradox Engine, Campaign of Vengeance, Hammer of Purphoros, Whip of Erebos, Healer of the Pride, Angel of Condemnation, Urza's Incubator, Coat of Arms

I have an Edgar Markov deck too, started out with the precon and built it up to a pretty good deck(if I do say so myself)

Thanks for all the comments and suggestions, wasn't active on TappedOut for quite some time.
I've made few changes, add those cards:
Bedevil
Champion of Dusk
Coalition Relic
Cordial Vampire
Forerunner of the Legion
Ruinous Ultimatum
Sorin, Imperious Bloodlord
Sorin, Vengeful Bloodlord

Took out:
Legion's Landing  ^Flip
Legion Lieutenant
Drana, Kalastria Bloodchief
Dreadbore
Harsh Mercy good card but way too many tribal decks in my group
Blood Baron of Vizkopa
Sorin, Solemn Visitor
Commander's Sphere

Comments and suggestions are more than welcomed. Might make some more changes and updates to all of my commander decks.

Cards I would like to add when they come out from the new Zendikar set:
Zagras, Thief of Heartbeats
Drana, the Last Bloodchief
Nighthawk Scavenger
Cards I would take out for them:
Mirri the Cursed
Gifted Aetherborn
and something else I'm not sure yet as I might add only 2 out of those 3.
Hopefully there would be few more interesting vampires or other cards in this set :)

Just thought id say i really like this deck +1 from me

dritchie thank you for the comment and +1 :)
I really like this deck too and I try to update it from time to time,
as in any other deck that can have them color wise, those cards can be included:
Malakir Rebirth  ^Flip, Sejiri Shelter  ^Flip and maybe even Kazuul's Fury  ^Flip.
And maybe this one too: Pact of the Serpent

Also my Xenagos dragons deck is really fun, maybe it will interest you too.
Xenagos Savageborn EDH
I've 9 edh decks atm, I try to keep them updated and on same power level more or less, but as I play in small groups or 1vs1 I've them 'set-upped' for that, and there aren't much graveyard hate I try to make them fun to play yet fun to play against..

Woh quite a lot of new vampires, sadly many are with the Blood Token mechanics, and as I don't want to change my deck too much there aren't really much of a point to include them, but I did found place for 4 new vampires:
+1 Edgar, Charmed Groom  ^Flip
+1 Henrika Domnathi  ^Flip
+1 Olivia, Crimson Bride
+1 Welcoming Vampire
-1 Vampire Nighthawk
-1 Bloodlord of Vaasgoth
-1 Necropolis Regent
-1 Zagras, Thief of Heartbeats
Comments\suggestions are always welcomed, trying to update this deck from time to time along my other decks.
