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 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 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 Maddening Cacophony just resembles a simple burn spells without much utility which ignores hexproof.

Disruption

For the disruption, that keeps us alive, we play counterspells and removal with Drown in the Loch and Bloodchief's Thirst. I like Drown in the Loch, because it's better than the original Counterspell after some turns in our deck. 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. Archmage's Charm is both card draw and a counterspell. And of course we also run the full playset of the now modern legal Counterspell, as it doesn't require anything to be a hard-counter, unlike Drown in the Loch.

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. Opt is just another cantrip, to find us the cards we need.

Manabase

We play 24 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 run Aether Gust, in case we play against Jund Death's Shadow and other RGx decks. Narset, Parter of Veils is very good in the control mirror, and when playing against storm. Drown in the Loch and Damnation are addtional removal spells, in case our counterspells don't do much. the third Cryptic Command can be a nice mana sink for the control mirror.

Tron:

I don’t think we need any sideboard against tron, as Surgical Extraction dismantles this deck already by itself.

Dredge:

Against dredge we play Crypt Incursion.

Burn:

For burn hate, we play Spellskite, which can save us a lot of life over the course of the game.

Heliod Company:

Against Heliod Company we don't sideboard, as Surgical Extraction deals with any kind of combo.

>Budget

The deck is quite expensive, at least for my budget, costing 280€ on cardmarket. This is definetily one of my most expensive decks, but I feel like playing with it is worth that much.
