Emrakul

The Zendikar block is a Magic: The Gathering block consisting of the sets Zendikar (October 2, 2009), Worldwake (February 5, 2010), Rise of the Eldrazi (April 23, 2010). The eponymous setting is a vast, untamed wilderness, whose few bastions of civilization exist primarily for outfitting treasure-seeking expeditions to distant locales. Colossal ancient octahedral stones called "hedrons" float in the sky (hedrons are the expansion symbols for all three blocks). A phenomenon known as "the Roil" causes frequent geological upheaval as it sweeps across the land. Unlike the previous two blocks, there is no multicolored theme (in fact, every colored card in the set is monocolored). Instead, the themes Zendikar and Worldwake revolve around lands, and a theme of an adventure or quest. Rise of the Eldrazi, while part of the Zendikar block creatively and for the sake of constructed tournament rules, is unique mechanically and is designed to be drafted on its own.

The first cards revealed from the set were a selection of basic lands, each printed with both a traditional frame and a full-art frame reminiscent of lands from Unglued and Unhinged. Cards with the "Landfall" mechanic have effects that are triggered when a land enters the battlefield under the card's owner's control. Adding to the land theme, there are a number of non-basic lands, including lands with a variety of enters-the-battlefield effects that were formerly restricted to creatures.

Zendikar also contains three Planeswalker: who first appeared in the Xbox 360 game Duels of the Planeswalkers; Sorin Markov, an all-new vampire character; and a second version of Chandra Nalaar, Chandra Ablaze, as previously foreshadowed in the novel The Purifying Fire.

To promote the "priceless treasures" tagline of Zendikar, original, authentic vintage cards were inserted into a limited number of booster packs, replacing the basic land. These cards were for collector and incentive purposes only, and were largely not legal for sanctioned Zendikar block play.
