The guilds featured in Guildpact are:

• The Orzhov Syndicate (white/black): While masquerading as a religion, the Orzhov are actually Mafia-like business people. With no economic transaction that isn't directly or indirectly under their control, they are directed by the Ghost Council of Orzhova, composed of the spirits of former Orzhov Patriarchs and Matriarchs. Teysa, Orzhov Scion, is the champion of the guild.

• The Izzet League (blue/red): The Izzet are responsible for almost all of the beneficial technologies and magics that keep Ravnica running. Unfortunately, their impulsive and reckless research principles mean that just as many have failed experiments with explosive results. Their guild leader is an extremely intelligent but temperamental and egotistic dragon wizard named Niv-Mizzet, the Firemind. The champions of the Izzet are a husband-wife pair of wizards named Tibor and Lumia.

• The Gruul Clans (red/green): The Gruul Clans were originally the Guild of Savage Nature, appointed to speak for and protect the people who lived in the harsh natural environments of Ravnica. As the city expanded over nature, the other nine guilds (specifically the other Green-oriented guilds) began appointing themselves as nature's defenders. Eventually phased out entirely by the rest of the guilds, the Gruul fractured into a myriad of different clans, all bent on destroying civilization. Some do it for revenge, others simply because they like to smash stuff. The biggest clan is ruled by the cyclops Borborygmos. Despite not being affiliated with any of the clans, the members view Ulasht, the Hate Seed as their champion.

Mechanics:

• Haunt (white/black): When a creature or spell with Haunt is put into a graveyard, it is removed from the game haunting a creature in play. When the haunted creature is put into a graveyard, the creature or spell with Haunt can perform an effect again.
• Bloodthirst (red/green): When creatures with Bloodthirst are played, they gain a boost to their power and toughness if an opponent was already dealt damage that turn. .
• Replicate (blue/red, Izzet): Spells with Replicate allow a given cost to be paid any number of times, and the spell is copied that many times.
