So over at our Facebook group, I did a poll to see what deck people wanted to see next. The overall victor was Davriel, Rogue Shadowmage.
I thought about it long and hard and I ended up deciding to go with a Dimir Surveil strategy with it, vs. a straight up discard deck. By utilizing the Surveil mechanic, it opens up the possibility for us to run Disinformation Campaign, one of the best payoffs for the strategy, to be able to continually force our opponents discard their hand while also getting us incremental value by drawing cards and then picking them back up whenever we Surveil.
I opted to stay away from cards like Mind Rot, as those types of cards are often good early but can be really terrible top decks late in the game. Instead, I want to rely more on cards like Thought Erasure, Dispersal, Davriel himself, and Disinformation Campaign to force cards out of our opponents hands. And in order to stop our opponents from drawing additional cards, we are running 2 Narset, Parter of Veils (not to mention, she allows us to dig for needed action).
We also are running a lot of creature control in this list as well. While we are planning to empty our opponent's hands, we know things will still hit the battlefield at some point. The most notable inclusions are the Tyrant's Scorn (another way to deal with all creatures, as well as force our opponents to discard their big creatures late in the game), and Enter the God-Eternals, another way for us to get a threat on the battlefield, gain some life, and remove one of our opponent's threats (while also being mildly annoying by forcing them to mill a bit).
We do have some different options for sideboard that we can choose from, should we want. Instead of negate, we can run Disdainful Stroke instead, it is a way to counter bigger things than our board wipes can blow up, and is also flexible enough to hit all spells over 4 CMC. I opted for 2 Dream Eater in the sideboard to replace Enter the God-Eternals in the planeswalker match up, as well as the addition of Ugin, the Ineffable and The Elderspell.
Overall, I feel like the direction I went is great, I made some tweaks from the original version after play testing, and I think this list feels pretty tight. What do you guys think? What did I miss? Anything you'd do differently? Let me know in the comments down below. And if you take this to an FNM, let me know how you do! I'd love to see your thoughts and results.
