Lorwyn

The Lorwyn block is a Magic: The Gathering expert-level block consisting of two sets: Lorwyn (October 2007) and Morningtide (February 2008). A third set, codenamed "Jelly", was originally planned as part of the Lorwyn block, but partway into the design of Lorwyn, it was split into a two-set block. Jelly was revealed as Shadowmoor, the first set of the new two-set block. The two blocks were linked together and rotated through the official tournament formats as a single, four-expansion unit. The primary theme of the Lorwyn block is tribalism.
