This is, quite simply, a format that utilizes only cards with the new card face (10th Anniversary cards, aka Type "10"). All cards with the old card face are banned, as are any normally non-tourney legal cards (World Championship decks & Unhinged, with the exception of Unhinged basic lands, which are legal). Promo cards with the new card face, however, are legal (such as Balance, Powder Keg, Accumulated Knowledge, etc.). No cards are restricted (yet

).
So, what deck would you play in this format? Affinity seems an obvious choice, but there is also the capability of running a deck with 4 Balances to keep that in check.
Thoughts?
