Core sets are reintroduced with Core 2019. The reintroduction makes it possible to move away from the Two-Block Paradigm, and create room to print three large standalone sets each year.
Throne of Eldraine is a top-down designed set, inspired by the romantic Arthurian legend of Camelot on one hand and Grimms' Fairy Tales on the other. Besides Grimm, the set covers a range of European fairy tales that come from a variety of sources. Mark Rosewater stated that he had been waiting 10 years to do a Grimm's world, comparing it to the LorwynShadowmoor block that had erred in being too true to the source material rather than hitting the tropes that players knew.
This is the penultimate moment of the Gatewatch's fight against Nicol Bolas. Darkness is coming to Ravnica. A conflict that could tear apart the world itself looms large, and the fragile peace between the guilds is strained to its breaking point. Now, with everything on the line, it's time to step up, prove your loyalty, and fight for your guild.
Ravnica is a city large enough to span an entire world. It is ruled by ten separate magical guilds, each of which oversees a different aspect of the city with its own unique personality and outlook on life.
On Tarkir, the home plane of Sarkhan Vol, five warrior clans vie for dominance on the fields of battle, each wielding its own unique blend of fierce battle magic.
