Lorwyn block
The Lorwyn block is the thirteenth block; unlike all previous blocks, it consist of only two sets: the large expansion, Lorwyn (File:Lorwyn logo.gif) and the small expansion, Morningtide (File:Morningtide symbol.png). The block came out in 2007-2008.
Keywords introduced in this block: Champion, Changeling, Clash, Evoke, Hideaway, Kinship, Prowl, and Reinforce.
Planeswalker, a new card type, debuted in this block. Tribal, another new card type, debuted in the previous block but was fleshed out in Lorwyn.
The race/class system is a major theme of this block. Each creature in the block belonged to one of the following nine creature types: Elemental, Elf, Faerie, Giant, Goblin, Kithkin, Merfolk, Shapeshifter, and Treefolk.
Mega Cycles
Three mega cycles exist across the block's two sets:
- Mono-colored legends: Each of these rare legendary creatures represents one of the main protagonists of the Lorwyn and Morningtide novels — Brigid, Hero of Kinsbaile, Vendilion Clique, Maralen of the Mornsong, Ashling the Pilgrim, Rhys the Exiled.
- Rare changelings: Each of these rare shapeshifter creatures has changeling and another powerful ability — Mirror Entity, Shapesharer, Cairn Wanderer, Taurean Mauler, Chameleon Colossus.
- Tribal lands: Each of these rare lands comes into play tapped unless you reveal a card in your hand of a certain creature type; there was one for each of the block's eight tribes.
- The tribal lands from Lorwyn could each be tapped for either of its tribe's colors — Ancient Amphitheater (giants, red and white), Auntie's Hovel (goblins, red and black), Gilt-Leaf Palace (elves, green and black), Secluded Glen (faeries, blue and black), and Wanderwine Hub (merfolk, blue and white).
- The tribal lands from Morningtide had different abilities from the lands in the previous set but shared their "tribal untap" ability — Murmuring Bosk (treefolk, counts as a Forest, can also be tapped for white or black mana at the cost of 1 damage), Primal Beyond (elementals, can be tapped for any color of mana but only to pay for elemental spells), and Rustic Clachan (kithkin, can be tapped only for white mana but has reinforce).
- Two cards, the common Shimmering Grotto and rare Mutavault, were associated with the changeling "tribe," but were not part of the cycle.
