Morningtide contains 150 cards (50 rare, 40 uncommon, and 60 commons). The theme of this expansion is tribal, based on class rather than race. Its expansion symbol is a depiction of a sun rising in the morning, or a flame. Morningtide is the second and final set of Lorwyn block. The following set, Shadowmoor, would not be part of the Lorwyn block, as originally announced, but the first set of a new block, codenamed "Jelly" and "Doughnut". However, these two blocks would rotate into and out of official tournament formats as though they were a single block.Morningtide introduced Tribal Equipment, Prowl, Reinforce, and Kinship. The set was accompanied by the novel of the same name, written by Cory J. Herndon and Scott McGough.
