Has Curfew been considered in the maindeck? Likely it would only be a consideration in a Reanimator heavy metagame, but it provides some nuts interactions with CIP effects. Primarily its used to bounce Shroud Fatties, but it has some uses on your side as well.
Notable Interactions w/ CIP effects include:
Court Hussar (old build)
Knight of the White Orchid (old build)
Fathom Seer *
Stone Forge Mystic **

It can also bounce your Grunt after you pay the Upkeep, which pretty good when you really need want it again vs. Dredge. On top of that, we know well that it slows down your opponent and saves your creatures from removal. The problem I see is that there aren't really any slots available. :/ How do the interactions I'm talking about work out when playing the Reanimator matchup? And in which other matchups do you board in Curfew.


Aside, I like how you guys keep updating the Primer to include new data; however, I think you ought to include the different lists that the authorities are playing. I know Matt still plays the old build, but Jeff plays the new build. Also, you ought to include card tags for people who are unfamiliar with obscure cards like KotWO.
