Description

Theros is a Magic: The Gathering block, consisting of the expansion sets Theros (September 27, 2013), Born of the Gods (February 7, 2014) and Journey into Nyx (May 2, 2014). The block is a "top-down" design inspired by Greek mythology.

The third set of the block, Journey into Nyx, was released on May 2, 2014. It is a small set consisting of 165 cards. The set completed the cycle of ten dual-colored "demigod" cards that debuted in Born of the Gods, as well as the cycle of ten "scry lands" that premiered in the first set of Theros. The set also includes the first green/white Planeswalker, "Ajani, Mentor of Heroes."

In addition to the block-wide mechanics, Journey Into Nyx features two new mechanics.

Constellation: This ability triggers whenever an enchantment enters the battlefield under your control, providing whatever bonus is specified on the card. To make room for it, Bestow and Devotion have both been scaled back, appearing on only five cards each; per Mark Rosewater, the dilution of those mechanics also represents the storyline's conflict between gods and mortals, and the latter's disillusionment with the former.[13]
Strive: this ability only appears on Instant and Sorcery spells that have targeting effects. Strive cards can have "any number" of targets, but the caster must pay an additional specified cost for each target beyond the first.
The Monstrous ability returns, last seen in the first set of Theros, replacing Born of the Gods' Tribute.
