As Mark Rosewater announced "we return to a Zendikar without Eldrazi and revisit the adventure world players fell in love with. It is a "land set" in the sense of the sets of the first Zendikar block, and all about adventure, exploration and reward.
Zendikar Rising contains 280 regular cards (101 commons, 80 uncommons, 64 rares, 20 mythic rares, 15 basic lands) and includes randomly inserted premium versions of all cards. Cards with alternate card frames have another card number than the original version. Like all previous Zendikar sets, Zendikar Rising features full-art basic lands (#266-280).[8] Borderless planeswalkers are numbered #281-283, borderless pathways are #284-289, showcase cards are numbered #290-313, extended artwork cards are numbered #314-379, and regular frame lands are numbered #380-384. The (non-exclusive) Buy-a-Box is #385, and the Bundle promo is numbered #386. Finally there are the FNM-treatment cards from the Universal promo pack numbered #387-391. Both regular and foil versions of the cards above #280 may be found in the Collector Boosters.

The Showcase cards are connected to Landfall mechanic. The card frame is themed around Zendikar’s hedrons, and the art style is intended to imitate bright-colored Travel Posters. The set features no new planeswalkers. The returning planeswalkers are Jace, Nissa, and Nahiri. Starting with Zendikar Rising, the mythic rares are changing their rate of drop. In the past, 1 in every 8 rares was a mythic rare. That is changed so that 1 in every 7.4 rares will be a mythic rare.[10] Equivalently, this is an increased chance, from 37 in 296 packs previously, to 40 in 296 packs now. Draft boosters have a dedicated MDFC slot.
