hymdall asked: Even though not all of them have been officially spoiled, is it a safe assumption that the 25 Zendikar Expeditions are all 10 Fetchlands(Onslaught/Khans and Zendikar), the 10 Shocklands, as well as the 5 new lands, which some are calling "laglands" or "tangolands"?

The twenty-five Zendikar Expedition lands in Battle for Zendikar are the five rare BFZ duals, the ten shock lands and the ten fetch lands.
