A terrific and thurough artcle, Mark. I almost hate to bring it up, but is there anything you'd like to add about Oath decks with the spoiling of Grafdigger's Cage?
Good question....lol.....I just posted it in the comments but I will post it here as well.
At the end of the day I feel that Brian Carey's building practice will become common place for all Oath decks. Maindecked Beast Within and Nature's Claim and even Hurkyl's Recall will still allow Oath to remain in a competitive capacity against Grafdigger's Cage. The biggest whammy is to blue decks with Tinker, Yawgmoth's Will and Snapcaster Mage, which have never really had to deal with this type of hate before....
