How it's played
The goal of the deck is simple enough. Get Yithians into the discard pile as quicly as possible while not only defending yourself but create openings in your opponet's defenses.
So, how is this accomplished you ask?
The crux of the deck is winning the Arcane Struggle and chaining together triggers from Lost Oracle and Studying the Void. Master of the Myths, Keeper of the Great Library, and Marcus Jamburg are you go to guys for this of course. To explain a bit further, in response to winning an Arcane Struggle, you can trigger the effects of Lost Oracle and Studying the Void per copy that ends up in your discard pile. Even if you find new copies because you were discarding more cards.
I.E. I win by 3 books at a story thanks to Master of the Myths with a Study in the discard pile. Revealing 3, one of which is a Lost Oracle, I discard all, and then now I can trigger Lost Oracles effect to discard to more cards from my deck, which hopefully hits another Lost Oracle or Studying the Void. Rinse and repeat and after an story phase or two the discard pile can fill rather quickly.
Other ways of filling one's discard pile that work in conjuction with the above triggers are The Festival and using Interstellar Migration itself to discard cards off the top of your deck.
As for the other cards in the deck, they're self explanatory. Festival plays tricks with Dark Passenger and helps get resrouced yithian cards into your discard pile while finding copies of Interstellar Migration, plus it accelerates if copies end up in the discard pile. Facless Abuductor, Pushed into the Beyond, Thunder in the East, Burrowing Beneath, Grasphing Cthonian, and Ice Shaft team up with Frozen Time to clear the path and remove any speed bumps in the way. Currently I theoryize that due to the amount of anti-hate this deck brings and how easily it finds it a player would need to maintain 4 'stops' (snow graves, flux stabilizer, etc..) while commiting to stories. It's just that unreal.
The Story Behind the Deck
Sunday after the FAQ was released Mike Mazur and I went went to Rhett Jenkins' place to see if we could come up with something that could cut through the guanlet. Armed with proxy'd decks and collections we played for hours while trying to come up any sort of an edge. It wasn't until late that evening that I began to stare at Studying the Void and began to think, "Man, this card is just so cool. Theres has just to be a way to make this worth it." Sure enough, Master of the Myths came to find first. Initially, I was just thinking that I could pull needed cards when I wanted them, but putting the pieces together I jammed it with nothing but yithians, removal cards, and a few support cards. Suprisingly, the deck worked! I was keeping all the decks we had from narrowingly defeating me.
I was in shock as to how well it handled everything. Still, I didn't believe it. I didn't want to take a 'mill' deck to gencon as I often found them unreliable and/or too easy to stop. However, with it doing so well with an unrefined list warrented investigation. This was when I re-discovered how good Lost Oracle is. With a second(third if you count Festival+Migration) way to fill the discard pile via arcane struggles... I blew my own mind. Now, I was discarding success tokens, rigging my draws with the answers I would need, filtering/accelerating with Festival, and doing it all in the span of 1-4 turns (average win was/is turn 3).
Whew, but I still needed to be sure. The following weeks were nothing but playtesting this deck to see if it could pull through in the most dire of situations. Shockingly, it exceeded every expectation as handled multiple problems from multiple angles with ease and grace. Personally, I'm not used to playing graceful decks. It just flowed together seemlessly.
Thanks!
I would like to use this space to thank Mike and Rhett for helping me peice this beast together and graciously playtesting with me almost nightly in a the few weeks we had leading up to the tournament. Performing the nigh-impossible wouldn't of been possible without your help.
Clarification
Wanted to quicly mention too. This deck, does not break any rules nor take advantage of any loophole. There was one at one point an where it could exploit a loophole that could allow cards like Studying the Void to be triggered an infinate number of times. But in the interest of the keeping the game as fair and fun for all as possible, I personally sought out FFG staff to put a close on said loophole. Appriopiate action was taken on site at the tournament.
That being said, this deck does explore some underused areas of the rulebook compared to your average deck.

In conclusion
That should be about it. As I gain time I'll whip up a full tournament report in it's own thread. Uhh... I don't expect this deck to last past the next FAQ. The Monday after we "figured it out" I attempted to appeal to Damon and Brad to ammend the FAQ to deal with an earlier iteration of the deck. Sadly a bit too late unfortunately, but after this deck proving out.. I wouldn't be suprised to see the banhammer.
That being said, I encourage all participants to share their decks and hope to see everyone at worlds! Now I shall open the doors for any questions or comments.
Thanks,
