They are not supposed too! You don't have to deal damage to start off the sanguine/exquisite combo, it will start it but so will life gain. I normally just attack with nighthawk or some other life linker. Black agro decks are some of the hardest to go against. They have out right death, life gain, and banding creatures. Wtf were they thinking putting that into one creature type?!? Don't take the comment above as anything other than suggestions. I like your deck. Have you collected different printing for your dark rituals?

Drop the dark rituals for sanguine bond/exquisite blood info it combo to make modern for tournaments or w/e. Why no captivating vampire???? I like the deck but the shade is a bit high for what it does for me, I get that it is to combo with exsanguate but I prefer the one that gives bloodlust 3 to vampires and infinite life/damage combo. Have you considered blood artist over highborn? Its the same cost for a smaller creature that does one loss/one gain for free.

I think you should go creature or go mill. You would have an easier time sending your casual black/blue mill to a competitive modern mill than what you have going on here. This is a good deck but its way too slow for modern. When I go to tournaments I have to deal with my buddies 4 turn goblin deck. When your mill deck can beat a deck like that it is fast enough, and I don't see that happening with mono blue.

Take a look at my elf deck, tell me what you think. Short bus Elves

Well the only modifications I would make would be to drop your creatures down to 4 of both token producers. The others are cool but not nessicary. You don't seem to be running any bounce, which to me is a must, so I would use the newly opened slots to add 4 cyclonic rifts, remove cerulean wisps for into the roil. That would leave 3 slots for either snap caster or call to mind. Snap caster is more difficult to deal with, but you can produce drakes by continually pulling back a pair of call to mind. After that it turns into side boarding specific counter cards to deal with different mechanics.
This is just my opinion. But then I enjoy playing blue. So I'm a little odd.

Do you own this deck or is it just concept right now?

Did you find something you liked?

No problem, I hate playing against that deck. My elves can't beat it if he goes first, and they play like slivers most of the time. If your friend dislikes goblins maybe he will like my elves better. Tell him to look my elf deck up if he is interested. Shot Bus Elves.

I love playing my blue deck, but my opponents do hate it. Most of it isn't standard, but the core is. Maybe you can find some stuff you like or want to add. http://www.mtgvault.com/zeddreth/decks/my-turn/

I like memory erosion, but drop traumatize for archive trap. At best you get 24 turn 5 with traumatize. At best with archive trap you mill them their turn one at worst its 13 cards for 5 mana. I am in the process of building a modern mill deck myself. Take a look, I could use the help/hints. http://www.mtgvault.com/zeddreth/decks/lobotomy/

My buddy has a 4 turn modern goblin deck. He wont let me see what's in it because of how I play but I have basically come up with the deck list from playing it so damn much. Have a look, you may find some hints or something. http://www.mtgvault.com/zeddreth/decks/short-bus-goblins/

Mage Slayer. Its an equipment that wont speed things up, but dragons with lone wolf ability on steroids.

I just posted my mill deck. Go and have a look http://www.mtgvault.com/zeddreth/decks/lobotomy/

Haha alright

The deck looks dirty. Decendents path! Potentially utvara or brood mother 4th turn is amazing! Only thing I could see for potential adds to speed it up would be a draw effect. Harmonize maybe?

I didn't see the combo between library. Nice. Nemesis is amazing and a game ender so by all means run him. Ashiok is really cool, have you thought about nightveil specter to go along with it? You already have circu to exile and haunting echos.

It looks a lot better. At this point just play it against as many decks as you can. The stronger your opponents deck the more information you will get on how to mod it. Only thing I can see would be the nemesis and ashoik they are both amazing but a little unnecessary. Nemesis will die and ashiok isn't as good as a jace. If library of leng is in there to do the same thing as reliquary tower I would just use the land instead.

Haunting Echoes + Traumatize will destroy most decks. Crypt Incursion for massive healing. Also I personally dislike Traumatize, it is amazing if you can play it 5th turn or before, but if you get it 20th its a 5 drop that will mill equal to a 2 drop. The crab is amazing, I run 4. You seem to have an amazing set up for a draw deck. If you look at Jace's Erasure as your core card (mechanic designed around,) then make everything about that card. With all 4 out its 4 cards off the top per card you draw. Amazing. I think that if you modified the deck to have more control/death remove most mill cards and make it about draw this could be an amazing deck. How I would do it, drop creatures down to a minimum. Crab, fog banks, archivists, and add a few Circu. Either elixer of immortality or psychic spiral to keep you from milling yourself out. Then draw draw draw, counter and kill everything you can. Let circu do his thing and control what they can play. Just a few ideas I have come across while building my mill deck. I will post it as soon as I finalize it. I am in the process of rebuilding for modern format.

Makes since. I said in the comment about removing the land that I had not made a deck designed to discard land.

The deck looks cool. Only add I can think of is Jace's Erasure. Jase's Erasure will.mill equal to the cards you draw. Also just switch day of judgment for wrath of god. No point in side boarding day of judgment with 8 board wipes. All in all a really cool deck.
