I wanted to build a deck that featured only Dimir cards. So if it doesn't have a Dimir watermark in it, I would deter from putting it in (There are a few exceptions as listed in the maybeboard). That' not to say I won't but I would like to keep the Dimir theme. The deck is to focus on the milling aspect of Dimir, either as a wincon itself, or use Lazav to smash face from copying a fattie. Many of the creatures have some form of evasion so Ciphering a Paranoid Delusions is very integral to the battleplan. Muddle the Mixture can be used to fetch out any of the other spells besides Psychic Strike is it much utility as it is a counterspell.

I would like to see if there are any better options that I'm missing out, particularly from the original Ravnica. I can also go a heavy Cipher route and have some fun, as this is meant to be a multiplayer kitchen table style deck.
