Journey into Nyx is the third and final set in the Theros block, preceded by Theros and Born of the Gods. The set is to be released on May 2, 2014. Journey into Nyx will be a 165 card expansion available in Booster Packs, Intro Packs, Event Decks, and Fat Packs. Cards will be translated to Chinese Simplified, Chinese Traditional, French, German, Italian, Japanese, Korean, Portuguese, Russian, and Spanish.
The set is expected to continue the core mechanics of the block, scry, monstrous, devotion, heroic, and bestow, but will also feature new mechanics. Cards that are already known to be included are the green-black temple, the red-blue temple, and the planeswalker Ajani. The cycle of gods will also be completed with the enemy color gods, Iroas, Keranos, Kruphix, Pharika, and Athreos.
Prerelease events will be held on April 26-27, Pro Tour Journey into Nyx (held in Atlanta) will take place on May 16-18, and the Game Day on May 24-25 will conclude the series of events that is directly connected to the Journey into Nyx release.
Your path has taken you to Theros, a plane beset by chaos. A mortal Planeswalker has forced his way into the pantheon of gods, who are outraged and threatened by his ascent. Drawing on the power of the god-realm of Nyx, they send creatures of pure enchantment to crush mortal armies. The heroes of Theros strive mightily as they face their greatest challenge: standing their ground against the gods. There can be no peace until the upstart is thrown down.
Here on Theros, you will forge a destiny to echo through the ages. Perhaps you will lead your fellow mortals on the battlefield, bolstered by your courage—or champion the pantheon as they struggle to right the natural order. Embrace your fate and become a legendary hero fit to rival the gods.
