new set Battle for Zendikar

Mechanics article
Zendikar Expedition lands are foil, full frame art nonbasic lands that will be numbered 1-25 in BFZ and 26-45 in the following set. An individual card will appear at about as often as a foil mythic rare (you will see them slightly more often because there are 25 of them versus 15 mythic rares). Ben B. from SCG said about 1 every 216 packs. The Zendikar Expedition lands are not part of the set, but will be playable in BFZ limited if you open one and the cards will be legal in the same formats as previously printed versions. BFZ will have the new dual lands, 10 fetchlands and 10 shocklands.
