I don't mean to toot my own horn, but I think the version I ran at the September Waterbury is probably still close to optimal for certain metagames.

The deck performs well against combo and control slaver, and can handle most other blue based decks, with the exception of Oath. Just be prepared to lose badly to Workshops.
The differences are that miscalculation really isn't a hard counter. Often you'll be playing control matches where they have 2 open for mana drain, and miscalc just doesn't help you.
I don't maindeck the duress because I hate fetching out sea and having it wasted. Games 2&3 against non-wasting control and combo they're a bomb of course.
Although Psychatog is a great creature, the deck really wants to drop dryad, and in most matchups (i.e. non aggro) I only want the tog when I'm going off with Yawgwill and need to win.
Tinker->X is completely broken, and will win a lot of games while taking up minimal space in your deck.
The maindeck naturalize and pernicious deed look overly defensive. The wishes should keep you out of trouble enough game 1.
Demonic Consultation looks unnecessarily risky. The deck is relatively redundant, and it doesn't have any single card that says "i win" besides yawgwill and maybe tinker, neither of which you want to consult for regularly.
In general you'll notice I run a lot more restricted cards. I feel that building these around an aggressive game plan and lots of early countermagic will win you games before your opponent knows what hits them.
The sideboard would obviously be tweaked quite a bit, but groundseals and energy flux would definitely stay.
The big X factor is that I really never tested this against Oath, since where I play Oath came out when workshops were popular, and I'd never play this deck in a workshop heavy metagame.
Hopefully this is helpful. Enjoy playing this truly fun and broken deck.
