Shadowmoor is a Magic: The Gathering block consisting of the expansion sets Shadowmoor (released May 2, 2008) and Eventide (released July 25, 2008). The block was originally conceived as a single set that was to be released as the third in the Lorwyn block, but it was ultimately released as a semi-independent two-set block. Shadowmoor was linked thematically to Lorwyn, and the four sets comprising the two blocks rotated through official tournament formats together.[1][2]
