It's a very nice concept with massive drawspells and the tutor while most cards have secondary effects.

I'd try out the deck with some cheap taskspecific discard as well (At least 5), and more sphinx's revelation.

I guess this is a test-deck!

Run 4 shriekhorn instead of tome scour.
I've tested the card in more than 200 games and it mills 5.something on an average, which means it mills more than tome scour.
It also allows you to disrupt any scry/manipulation of top card that an opponent may have.

If you dislike shriekhorn try out dream twist. In the long run it mills one more than tome scour.

Interresting concept.
Let us know if it wins at a tourney :D

With all the 5-6 mana costs this deck needs to play 25 lands at minimum...
Once you got that much land You would also prosper by using at least 5 discard cards or cheap removal.

White adds plenty to mill-designs depending on strategy type, but yes, white is best for sb options, as UB does not have so many tools against artisfacts or enchantments as white does.

And there's allways a reason as to WHY the meta consists of more than 50% of 3cc.

Cutting a color always rob you of a lot of options. Most of the meta runs 3colors+
If dismember is to harsh, support with crypt incursion.

Damnation is damned slow. I have been toying with black sun's zenith for that reason against the faster aggro out there, but in the end I might use both in sb for versatility

And get rid of flooding as it is the least milling card among mill-cards out there. No opponent will use the lands once they are enchanted and even decks with a low amount of mana can play through it by using other lands. I've tested most millcards out there extensively and chronic flooding won't be of any use unless you use something that tap lands. Mursh's suggestion of propaganda might justify flooding, but don't count on it too much. For that mana mesmeric orb does a lot more milling and works no matter what land they tap :D (And it works even better with propaganda than flooding will)

steel overseer instead of lodestone myr?

KJS3: I hunt!
But I can use a pointer now and then :)

SCHOLAR:
When I design decks I usually do massive testing to find the right numbers, which means I usually remember what everyone else use as well as what I prefer to use, so I can follow you in being independant about cardpicks.
I would like to point out that most registered top 8 wins with modern mill uses shelldock isle, so the card must have something going for it :D Beyond that fact I personally think the favored number of 3 shelldock is way to much, and as stated I'm starting to use only one. My statistics for it is that it's only working a little above 50% of the time, but when it works it usually delivers the kill. It can be used in different ways as well.

It's not always that people notice what shelldock isle can be used for:
When I play one of these I always study the 4 cards carefully, evaluating if it's better to get a fetchland in play to support some crabs, or if I can cast entering from breaking/entering to steal something valuable from a grave, or if I can count on using mind funeral with enough lands gone from the opponent library to be lethal.

Could be he works within a group so they need certain identifiers to search for each others material.

For your efforts in posting your esper-mill you are invited to the pro-miller forum that I am trying to start up:

No shelldock isle? Most pro's use 3, I prefer 2 but might cut down to 1 in the future.

I'm trying to break aggro with UBR burn&mill, but it will take a long time for me to do it the way I always do it.
Slow considerate progress and lots of tests with proxy-decks.

You might find "godica"'s sideboard usefull

Fog only stops "DAMAGE" Emrakul still gets to attack, which lets it trigger annihilate, and fog certainly does not stop an annihilate trigger :D It will be hard to play fog without lands, and emmy can remove 6 permanents each turn. The above can definitely not play 7 lands a turn...

The real danger is combodecks not based on attacking with creatures and anything with annihilate...
SB needs something against emrakul...

Brilliant colorpick in getting an insane number of "fog" effects.

I would work a lot on the mana to make it less lifeeating, which would make you able to cut angel's feather, and by adding more ghost quarters you will be able to slow down tron. Rest in peace will protect you from emrakul, tasigur and gurmag angler, so that is a sb solution you might want. eldrazi green currently sees more topplay than red deck wins does.

Shriekhorn might be a better pick than tome scour, especially since you may time it :D
I've also run extensive tests with tomescour and shriekhorn, and on an average shriekhorn mills a fraction more than tome scour
(Meaning that on an average it manages to mill 6 cards a lot more than it mills 4)

With my grixis I've already played around 50 games against infect, and the chancellor has been hardcast at least 4 times. I don't play the chancellor for it's creature aspect but for it's mill during the openinghand. Granted this setup works best when you also use surgical extraction. But in 4 out of 50 games the chancellor is hardcast, and in one of these games I got to play 3 chancellors in a row (Two times I blocked an infect critter boosted with "become immense" and when I played the third chancellor infect was totally out of steam and died)

So far My paperstrips tell me that the chancellor is dead less than 1 out of 10 times, as it is either cardcast (4 out of 50) used as faith-fodder, or revivied with entering (from breaking//entering, 1 out of 50, but you need red mana for this) or shelldocked into play. These examples does not count as performing it's main features, which is milling due to being in the hand. The statistics for that is always above 50% but I haven't pinpointed an exact number as I only use it when it performs better than 50% and it does that a lot.

My matchup% versus infect is 50% with 5 "blank cards" in the main-deck, meaning that it wins half of the time with 5 cards that does nothing at all, not even counting as lands, so anyone could find 5 extra cards to experiment against infect with.

But if you don't like chancellor, you just don't like him. Just be aware that when you've tested the chancellor you have probably remembered all the times he was drawn lategame and forgotten all the times he milled 7 for free. It's human to remember the bad times better, which is why I use paperstrips.

Anyway's it takes time to restructure mill from UB to RUB and the mana will be difficult to toy with, so if you feel better with UB just go for it. I've had a lot of success with UB myself :D

I like your answers and they seem solid arguments with room enough for weaknesses.
I rarely discuss weaknesses within my own mill-builds as I tend to solve them all longterm :D

I currently advocate chancellor of the spires as I've won a 3-4th place with them in a UB mill, and have been using them since without any regret. (Currently in a grixis mill with faithless looting) I know they work because I track all my cards during tests against proxy-decks, using paperstrips and noting on each card when it works or not. With more than 200 games keeping track of chancellor of the spires I can tell you that the best amount for using them is 3, not less and not more, as long as it is in a UB-brew. Chancellors will allow you to surgical extract almost at the opening of hands (your opponent's upkeep if they start the game) which allows you to remove glistener elf or inkmoth fairly often before they even get a card in play.

I'm also seeking out pro millers to start up a forum for all things modern mill, with the aim of discussing changes in the meta. At least 3 other people in here are trying very hard to get personal designs to become mainstream.
(Not counting myself) Look for it here:
http://www.mtgvault.com/wickeddarkman/decks/forum-competitive-modern-mill/

One thing is design, another is winning.
Since you tag it as competitive and can answer most questions on the contents I asume you've played it at tourneys.
How far into top 8 have you gotten with it? (Or related past designs)

I'd also like to know how you deal with affinity, elves, infect and merfolk in regards to sideboard...

Go take a look at my stuff if you wonder why I ask :D

Sideboarding is always an artform, especially with decks that has large weaknesses.
Most of the time when I design a deck I usually end up with most of the original deck in the sideboard.

I believe that there are plenty of "fun" cards out there to be used in most designs, it just take a lot of tweaking to get them to fit inside a competitive deck. But cards I consider fun are not always fun in the eyes of others! For me fume spitter is a fun card to play because noone else would consider playing it, so I would spend some time on trying to make it fit in the deck. I would find some sadistic glee in playing a spitter on turn one and a spellskite turn 2 against infect, imagining how their insides must be twitching trying to get around that sort of setup. Fun cards take time to find though, and a lot more time to insert propperly into a deck.

If you want to use mimic vats, first go through alternative cards, and reach for anything that could produce the same or a related effect (collective company?). Then think of the worst possible matchup, proxy it and start finding ways to protect your concept. Just go for it :D (And let me know if it wins!)
