Dimir Control Brewing

[dim pawn]

Hey all, I am getting into pioneer and originally I was going to go mono-white humans but I decided to go with a Dimir Control pre-con and I decided I wanted to start upgrading it. I would like some advice on what to put into the deck, I want to make it a control and mill deck, I am open to all suggestions, even switching colors possibly. The deck listed is mostly precon cards mixed with cards I had already. I look forward to reading all suggestions 🙂

I think for this sort of deck neither dimir control or mill is the best so I’d stay to one side

But the more reliable thing imo is dimir control

But if you wanna mill [[tashas hideous laughter]]

Each opponent exiles cards from the top of their library until that player has exiled cards with total mana value 20 or more.
