IMHO theres not reason to play MUC unless you're jamming Back to Basics (and shackles to a lesser extent), if you're not running B2B then adding any other color would make the deck stronger, so I think maindeck B2B is a must.

This is the rough list I'm working on...I am unsure about 2x Fact or Fiction, I might very well replace them with 2 more win cons like Clique or even Teferi. The idea is to keep the board clear, flash in a guy eot and lock the board with Standstill. I think repeal is vastly underrated...it slows down alot of decks for very little mana, 20/20 tokens, flipped delvers, aether vials etc and is value with Snapcaster Mage.
