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).
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.
Cycles
- Mono-colored legends mega cycle: A cycle split between Lorwyn and Morningtide, legendary mono-colored cards for the main protagonists of the Lorwyn and Morningtide novels — Ashling the Pilgrim and Brigid, Hero of Kinsbaile from Lorwyn were joined by Rhys the Exiled, Vendilion Clique and Maralen of the Mornsong in Morningtide.
- Rare changelings mega cycle: Each of these rare creatures, one for each color, has the shapeshifter creature type and the changeling ability. Mirror Entity, Shapesharer, and Cairn Wanderer were printed in Lorwyn, while Morningtide finished off the cycle with Taurean Mauler and Chameleon Colossus.
- Tribal lands mega cycle: Each of these lands comes into play tapped unless you reveal a card in your hand of a certain 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.
