The decks to beat section have been updated with 7 of the 8 decks from the elemination rounds at BSK 2013. The missing deck is Brorsan's winning WW list, but the other sweet decks can now be viewed in full glory. I'm sure I'll discuss some of these decks in more detail in the future, as well as some of the decks that didn't make the cut (in particular GaJol's reanimate deck was awesome).
The Djinns and Efreets are showing up in big numbers this time. As control has been somewhat weakened, the big Arabian Night's creatures can dominate the board more easily.
Freespace's 5c Machine Head.
The only card played in all 8 decks is Strip Mine. Some other cards that are played in a majority of the decks include Black Lotus, Sol Ring and Mishra's Factory. The most copies of a non-land card is Berserk, with no less than 16 copies in the top8. I guess that cards like Moat, Terror and City in a Bottle will become more popular
