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 Lorwyn block, but partway into the design of Lorwyn, that block was changed to a two-set block. Jelly was revealed as Shadowmoor, the first set of a second two-set block. The two blocks were linked through synergy and rotated through the official tournament formats as a single, four-expansion unit. The primary theme of the Lorwyn block is tribalism.

Lorwyn
The designers of the set were Aaron Forsythe (lead designer), Mark Rosewater, Paul Sottosanti, Brady Dommermuth, Nate Heiss, and Andrew Finch; the developers of the set were Devin Low (lead developer), Bill Rose, Matt Place, Henry Stern, Mike Turian, and Doug Beyer.

Lorwyn is set in a more traditional fantasy world, inspired by Welsh folklore. The plane is a pastoral world inhabited by several major races: boggarts (goblins), faeries, elves, giants, treefolk, merfolk, elementals (including the flamekin) and kithkin.

Five theme decks have been released as part of the set, one more than the standard four-per-expansion, which has been a long-time trend. The preconstructed theme decks are: "Kithkin Militia" (White), "Merrow Riverways" (White/Blue), "Boggarts' Feast" (Black/Red), "Elvish Predation" (Black/Green), and "Elementals' Path" (White/Blue/Black/Red/Green).

Morningtide
As revealed in an advertisement in the trade publication ICv2 and later confirmed by Mark Rosewater in his column, Morningtide expands upon Lorwyn flavor and theme by focusing on at least five classes (Soldiers, Shamans, Wizards, Warriors, and Rogues) as well as a few minor class-based tribes (Druids, Archers, Knights, Clerics, and Assassins) in addition to the eight races of Lorwyn (Kithkin, Merfolk, Faeries, Elementals [Flamekin and Greater], Goblins, Giants, Treefolk, and Elves). Additionally, three new mechanics were keyworded with this expansion, namely; Prowl, Reinforce, and Kinship.

Four preconstructed theme decks have been released as part of the set. The theme decks are "Battalion" (White/Blue), "Going Rogue" (Blue/Black), "Shamanism" (White/Black/Green), and "Warrior's Code" (Red/Green).

Tribal
The block has a tribal theme, focusing heavily on creature subtypes, revolving around eight primary creature types. Each of these appear in two or more colors, with one as the primary color:

Mechanics
Lorwyn saw the release of an entirely new card type, the Planeswalker. This marks the first time that Wizards has added a new card type to the current game, as Alpha introduced all current card types, other than the type "Tribal". A single tribal card,, was printed as a future-shifted card in Future Sight. Another significant creature type is the shapeshifter type, all of which have the ability "changeling." Creatures with changeling have all creature types. This plays into the tribal mechanics which grant bonuses to creatures of certain types. Though these changelings counts as humans for the purposes of the rules, no humans are found in the world of Lorwyn, or are printed on the cards. This marks yet another fundamental change of the game, as this was the first set to have no humans since their introduction as a creature subtype in Mirrodin. (Although humans had been in all sets since the beginning of the game, they did not have their own subtype until Mirrodin, instead only having subtypes based on their classes.) However, several of the planeswalkers, although they have no creature type, are physically humans.

The Lorwyn block features the new keywords champion, clash, evoke, and hideway. When a creature with Champion [a type] comes into play, it's sacrificed unless another creature of that type you control is removed from the game (that card is returned to play when the card with champion leaves). Clash involves two players revealing the top cards of the libraries. The person who reveals the card with the highest mana cost wins the clash and gets a bonus on the card played. If a creature is played by paying its Evoke cost, it is sacrificed when it comes into play. Hideaway, which appears on a cycle of rare lands, lets you "hide" (exiling facedown) a card "away" for later.

The new mechanics introduced in Morningtide are prowl, kinship, and reinforce. Cards may be cast for their prowl cost if you have dealt combat damage with a Rogue, often providing some additional effect. Kinship rewards players for revealing creatures that share creature types from the top of their libraries. Reinforce allows you to discard the card with Reinforce, plus a small mana cost, to put +1/+1 counters on creatures already on the battlefield. Morningtide also has a cycle of tribal equipment.
