Dimir Mill Control

>Gameplan

The gameplan of this deck is pretty simple. It slows the opponent down and buys more time for your Mesmeric Orb to do its job. An important thing to remember is, that tempo has to be sacrificed in favor of disrupting the opponent. So rather than a T2 Mesmeric Orb, just keep the two mana open for a Mana Leak or Drown in the Loch.

Mill

So at first we have a playset of Mesmeric Orb for the main win-condition. It also mills ourselves, but as we have some more mill-accelerants our opponent is most likely getting milled first. For the mentioned mill-accelerants we have Glimpse the Unthinkable and Maddening Cacophony. I like to think of mill as a more fancy variant of burn, but it doesn't want to count to 20, it counts to 60. So Glimpse the Unthinkable and Maddening Cacophony just resemble simple burn spells without much utility. With Maddening Cacophony we are able to mill a large chunk of the opponents deck at once, if we have acquired enough mana to play this and still have mana open for interaction. Archive Trap is nice, most of the time basically a free mill spell.

Disruption

For the disruption, that keeps us alive, we play eight counterspells with Drown in the Loch and Mana Leak. I like Drown in the Loch, because it's better than the original Counterspell when played in the late game, as it's able to remove or counter literally anything at any time. It's also one of the reasons, why I don't play Ashiok, Dream Render, as it leaves the opponents graveyard empty, disabling Drown in the Loch. For the boardwipe, we play Damnation, good against go-wide strategies. Cryptic Command is in there, just because of its extreme versatility.

More Control

For additional control we have Surgical Extraction, representing another reason not to exile the opponents graveyard. It dismantles any combo strategies and is otherwise pretty good against any deck that plays some 4-ofs. With Surgical Extraction we have the option to shock ourselves instead of paying the mana cost. This might seem favourable, as we want to keep our mana for interaction, but I prefer waiting one or two turns and paying the mana, as our life total is expected to get pretty low when playing against aggro and burn strategies, and we don't want to help those decks out by paying two life and lowering it even further. The last reason to keep graveyards filled is Visions of Beyond. If we have the opponents graveyard filled with enough cards, it basically is as good as an Ancestral Recall. And thats pretty damn good.

Manabase

We play 23 lands total. For a nice dimir mana-base we play Drowned Catacomb, the new Clearwater Pathway and Watery Grave, plus 11 basic lands.

>Sideboard

For general sideboarding options we have the third Damnation, in case we need more of them in some matchups. 4 Ravenform are in there as well, providing artifact hate. The fourth Surgical Extraction is in here, to weak combo decks like Hammer Time, Tron or Heliod Company. In addition we run a Swamp in sideboard, as a little more black mana can be nice when sideboarding in a lot of black cards.

Tron:

I don’t think we need any sideboard against tron, as Surgical Extraction dismantles this deck already by itself. We may sideboard in the fourth Surgical Extraction in this matchup.

Dredge:

When playing against dredge, we will swap out Damnation for Crypt Incursion. Crypt Incursion is nice grave-hate and also gains us so much life, no boardwipe to protect our life-total is needed. Crypt Incursion may be good against other aggro-strategies as well. ´

Burn:

For burn hate, we play Spellskite, which can save us a lot of life over the course of the game. We will ditch Damnation for that matter, as burn is not really going wide and we already have some removal with Drown in the Loch.

Heliod Company:

Against Heliod Company we run Everlasting Torment, shutting down their life-gain synergies. The fourth Surgical Extraction might be useful here as well.

>Budget

The deck is quite expensive, at least for my budget, costing 350€ on cardmarket. This is definetily one of my most expensive decks, but I feel like playing with it is worth that much.
