Removed the first 17 cards from the set. Only 14 more to go.

If you've already got an Ashnod's Altar, an Exsanguinate, a Debt to the Deathless, why not add a Teysa, Orzhov Scion and a Darkest Hour to give you another win-con?

Maybe even toss in a Phyrexian Altar to boot, so that the Teysa/Darkest Infinite Sacrifice Combo can pay for your triple/quadruple color symbol spells and your Extort costs.

Overall a very nice deck. The whole Extort mechanic seems very well suited to multiplayer EDH.

Dumping 'Maybeboard' here, to keep the deck as clean as possible:

• 1x Angel of Despair #Control
• 1x Aura of Silence #Tax
• 1x Bloodgift Demon #Card_Advantage
• 1x Deathbringer Liege #Control
• 1x Dictate of Erebos #Tax
• 1x Elspeth, Sun's Champion #Control
• 1x Ghost Council of Orzhova #Drain
• 1x Gray Merchant of Asphodel #Drain
• 1x Merciless Eviction #Control
• 1x Ob Nixilis of the Black Oath #Drain
• 1x Ob Nixilis Reignited #Card_Advantage
• 1x Obzedat's Aid #Utility
• 1x Profound Journey #Card_Advantage
• 1x Rhox Faithmender #Lifegain
• 1x Rout #Control
• 1x Ruinous Path #Control
• 1x Sorin Markov #Drain
• 1x Spectral Procession #Utility
• 1x Sublime Archangel #Utility
• 1x Teysa, Envoy of Ghosts #Tax
• 1x Teysa, Orzhov Scion
• 1x Wurmcoil Engine #Lifelink

With all the drain and extort you have Karlov of the Ghost Council would be pretty good. He benefits from the life gain and provides removal/control.

@Sa-Kage I think you are right. He'll get a spot for now.

Dumping the remaining maybeboard here and removing the prototype flag.

Cheers

Why do you have Necrotic Sliver in the deck?

@freeall he is a 'destroy target permanent' on a 2/2 body. That is pretty good, no?

Cheers

Nice job! +1 for sure. I have a Tiny Leader version of this.. Still needs some tweaks though I think. I'll post it

http://www.mtgvault.com/devilyouknow/decks/karlov-tl-extort/

I would assume he runs Necrotic Sliver for the same reason I do, recurrable Vindicate is really really good.

Swapped Obzedat, Ghost Council to the 99 and upped Karlov of the Ghost Council to commander, as it seems likely that I'll have enough lifegain triggers to use his exile ability frequently.

Cheers

How about adding Greed to the deck? Might be good for card advantage.

@logansullivan I think that Greed is pretty good, but I'm not sure there is anything I would take out for it (it is CMC4). What do you think I should drop?

Cheers

possibly Painful Quandary because it really doesn't do enough for the mana cost

Ghost Council of Orzhova for a cheap sac outlet and life gain triggers for ?

Nice deck! I just noticed that most of the cards in your mainboard are 3 cmc or lower, making it entirely possible to make a second Karlov deck in Tiny Leaders. I tried it, it works great. However, in Tiny Leaders, I think you will find that Karlov is more for dumping evasion on and beating than removing. Removal on him in Tiny Leaders is just a side effect, if you happen to need it. Anyways, great deck. +1 for sure!

Great deck, good picks. I think Unspeakable Symbol might put some of that lifegain to good use, and has some minor synergies w/ other +1/+1 counter cards.

What about:
Curse of the Forsaken

Righteous Cause may be good
