Simple Dimir Control using Surveil to create value with late game threats
Enhanced Surveillance will allow us to have such a variety of options available to us throughout the game, and will almost all the time give you a setup for your next draw every time you counterspell or use one of your removals.
Very good win conditions in the form of Doom Whisperer and Dream Eater, both of these are very threatening, as Dream Eater can enter instantly at the end of the opponent's turn, bounce his most menacing permanent, surveil 4 (or 6!) and be ready for attacking on the next turn, with your best option being available almost all the time since you just dug it out of the next 6 cards...
Doom Whisperer is extremely strong with 6/6 flying trample akin to those demons we love so much and for 5 Mana too! It can be played on curve and force your opponent to react of be defeated very quickly, and if you have life to spare you can always surveil 2 (or 4!) at the end of your opponent's turn to consult your options. The only disadvantage is that he had to be cast on your turn, leaving you open, which at an unfortunate timing can be very damaging and cause you to lose control.
I have included Chemister's Insight which most of the time will be tossed in the graveyard from your deck with surveil. While some people argue that doing so would kind of waste a chance of use it twice, and they are not wrong, but it also means you "sort of" are gonna add two option to your plays rather than only one that can be repeated twice. Surveying a Counterspell on top and chemister's insight in your graveyard is IN-CRE-DI-BLE since if you don't use your Counter by the end of his turn, just draw 2 and there you go. Same scenario is also true for removal.
Notion Rain can be a bit awkward to play and is probably among the more ambiguous choice I've made for this list, however i really like that you can surveil 2 (or 4!) before drawing 2, potentially adding a chemister's insight to the grave in the meantime. This is going to be used mostly as a late game play to refill your hand while keeping 3-4 mana opened for a swift Sinister Sabotage or Vraska's Contempt. Playing this on turn 3 would be highly unadvised and is really not why it was put into the deck.
Disinformation Campaign is really interesting due to the gap in card advantage it gives you and just the sheer amount of opportunities within the deck to add value to it by just re-using it whenever you have a spare 3 mana. This along the course of a game will simply dismember your opponent's hand little by little while filling out your own. Pretty neat card and probably one of my favorite among the list.
Hope you enjoy the list and if you do try it yourself let me know how it went and how you would change it, there are so many different ways of exploiting the core of this deck I can't wait to see what you guys can come up with.
