Guildpact

Guildpact is the thirty-seventh Magic expansion and was released February 5, 2006 as the second set in the Ravnica block. The prerelease was on January 21, 2006.

Set details
Guildpact contains 165 black-bordered cards (55 rare, 55 uncommon, and 55 commons). Its expansion symbol is wrought-iron design with three “branches” meant to evoke the three-guild nature of the set as well as the urban theme. Guildpact expanded on the Ravnica block themes of multicolor and hybrid, adding three new guilds to the environment: the Orzhov Syndicate (white/black), the Izzet League (blue/red) and the Gruul Clans (red/green). The set also included the first creatures with exactly four colors, the Nephilim.

Marketing
Guildpact was sold in 15-card boosters, three preconstructed theme decks and a fat pack. The decks and the fat pack contained a Pro Tour Players Card. The booster packs featured artwork from Djinn Illuminatus, Rumbling Slum and Graven Dominator. The prerelease card was a foil alternate art Djinn Illuminatus. The release card was Gruul Guildmage. The set was accompanied by the novel of the same name by Cory Herndon. Additional art for several tokens was created for Magic Online.

Storyline
The Guildpact has kept Ravnica stable for thousands of years. But with ten guilds vying to become the dominant force on the planet, there's always a chance that things will break down. Guildpact continues the story of this massive city, and introduces players to three more guilds. The Gruul ravages the streets. Teysa leads the Orzhov Syndicate to "cleanse" them. And Agrus Kos doesn't give a damn.

Misprints

 * Hypervolt Grasp was printed with a Gruul symbol as watermark, despite being an Izzet card.
