Ravnica is one of Magic: The Gathering’s defining settings: a plane-spanning city whose politics, religion, commerce, crime, and even garbage collection are shaped by ten powerful guilds. Each guild corresponds to one of Magic’s ten two-color combinations, so choosing a guild is both a story preference and a shorthand for a style of play.
The short answer: Azorius makes the laws, Boros enforces justice, Dimir trades in secrets, Golgari manages rot and renewal, Gruul rejects the city’s institutions, Izzet invents dangerous things, Orzhov turns faith into debt, Rakdos thrives on spectacle and violence, Selesnya preaches collective harmony, and Simic engineers new life. None of those descriptions is the whole story. The fun is how each guild thinks it is essential to a city that can barely tolerate the others.
For a first-party overview, Wizards maintains an official Ravnica plane guide. This guide expands on that foundation with the character of each guild, how the mana colors express its philosophy, and what sort of deck it suggests.
The ten Ravnica guilds at a glance
| Guild | Colors | What it does in the city | Familiar gameplay identity |
|---|---|---|---|
| Azorius Senate | White–blue | Law, bureaucracy, public order | Control, taxing, detaining, flying creatures |
| House Dimir | Blue–black | Intelligence, secrets, infiltration | Disruption, card selection, graveyard schemes |
| Cult of Rakdos | Black–red | Entertainment, brutal performance, chaos | Aggression, sacrifice, risk for reward |
| Gruul Clans | Red–green | Rebellion against urban civilization | Large creatures, combat, destruction |
| Selesnya Conclave | Green–white | Community, nature, spiritual unity | Tokens, counters, wide creature boards |
| Orzhov Syndicate | White–black | Religion, debt, commerce, hierarchy | Life drain, sacrifice, recursion, taxes |
| Izzet League | Blue–red | Engineering, experimentation, infrastructure | Instants, sorceries, spell triggers, artifacts |
| Golgari Swarm | Black–green | Decay, sanitation, regrowth | Graveyard value, sacrifice, recursion |
| Boros Legion | Red–white | Military organization and enforcement | Combat pressure, coordinated attackers |
| Simic Combine | Green–blue | Biological research and adaptation | Counters, ramp, growth, evolving creatures |
The gameplay descriptions reflect common themes across Ravnica releases, not permanent rules imposed on every card of those colors. You can build a white-blue creature deck or a red-green control experiment; guild identity just gives designers and players a useful starting vocabulary.
Azorius Senate: order through laws and procedures
Colors: white–blue. Azorius believes society works when it is governed by procedure. That can mean genuine public safety, but Ravnica frequently portrays the Senate as so devoted to process that real people disappear under layers of regulation. Its courts, legislators, and law-enforcement systems show what happens when white’s desire for order joins blue’s pursuit of perfect systems.
In gameplay, Azorius often controls how quickly other players can act. Countermagic, taxation effects, tempo interaction, and evasive creatures fit the flavor. If you like answering threats one by one and winning after a patient setup, Azorius may be your guild. If you dislike long rules discussions, you may find it a little too thematically authentic.
An Azorius Signet or Hallowed Fountain is also a reminder that the guild is a recognizable color-pair identity on ordinary mana-fixing cards, not just on legendary characters.
House Dimir: knowledge, influence, and the unseen hand
Colors: blue–black. Dimir’s public presence is deliberately slippery. Its reputation centers on spies, assassins, hidden information, and manipulation. In Ravnica, knowing what someone intends to do can be more useful than confronting them openly.
Blue offers planning, card selection, and access to information; black offers ambition, secrecy, and willingness to use uncomfortable means. The result is a guild that prefers to control a situation before opponents realize a conflict has started.
Dimir-flavored decks often use evasive attackers, disruption, graveyard interaction, milling, or theft of resources. Mill is an especially visible theme in some sets, but not every Dimir deck is a mill deck. The underlying appeal is information advantage: seeing options, limiting the opponent’s good choices, and using threats that are hard to answer cleanly.
Cult of Rakdos: spectacle with sharp edges
Colors: black–red. Rakdos is simultaneously an entertainment institution and a nightmare. Its performers embrace danger, excess, and spectacle. The guild’s association with labor, carnivals, and shocking public shows gives it a strange civic function even while its culture terrifies everyone else.
Red’s appetite for freedom and sensation blends with black’s hunger for personal gain. Cards aligned with Rakdos are often aggressive, involve sacrifice, or offer a potent effect at a real cost. Sometimes the fun is winning with calculated recklessness rather than playing around every possible answer.
If a deck asks you to sacrifice a creature for additional damage or draw, think Rakdos. The guild is an excellent lore explanation for why black-red Magic often turns apparent disadvantages into fuel.
Gruul Clans: the city’s furious outsiders
Colors: red–green. The Gruul reject the relentless expansion of Ravnica’s civilized districts. Their clans identify with the wild places and older ways displaced by the city. Outsiders see smashing and raids; the Gruul see resistance against institutions that took their land and identity.
The color pair brings red’s anger and freedom together with green’s instinct and physical power. In gameplay, the result is usually straightforward pressure: large creatures, extra combat damage, haste, and destruction of artificial obstacles.
A Gruul deck can be simple to pilot without being mindless. You still decide when to commit another creature, whether to hold a combat trick, and how to close before a controlling opponent stabilizes. If you want your guild’s philosophy expressed as “less debating, more attacking,” Gruul will cooperate.
Selesnya Conclave: harmony, growth, and uncomfortable conformity
Colors: green–white. Selesnya frames the world as a community of interconnected life. The Conclave speaks of unity, spiritual purpose, and care for the collective. That sounds soothing, until you consider how little room an intensely unified group may leave for individual dissent.
Green emphasizes the interdependence of nature; white emphasizes a shared social order. Together, they form the guild most associated with creature communities and the idea that the whole should be stronger than its members.
In cards, Selesnya often wins by creating many creature tokens, protecting them, and improving the entire board. A token army rewards careful sequencing: a small creature can become valuable when it contributes to a team-wide enhancement or gives you additional bodies to defend with. If you like building rather than destroying, the Conclave is an appealing home.
Orzhov Syndicate: debt is eternal
Colors: white–black. The Orzhov combines religious hierarchy, contracts, commerce, and coercive debt. Its power is not just financial. Obligation can continue after death, producing one of Ravnica’s more chilling ideas: an institution that treats souls as assets.
White’s hierarchy and rules combine with black’s self-interest. The resulting guild can cloak exploitation in legitimate-sounding process. Compared with Rakdos’s public chaos, Orzhov often feels terrifyingly organized.
Gameplay commonly revolves around life gain and loss, sacrifice, afterlife effects, recursion, and taxing opponents. A white-black deck may lose small creatures without falling behind because death itself triggers another benefit. You can think of Orzhov as a value engine that sends the bill to everyone at the table.
Izzet League: science with inadequate safety rails
Colors: blue–red. The Izzet maintain and invent much of Ravnica’s infrastructure. Their experiments can be genuinely ingenious, but curiosity and ambition frequently outrun caution. Under the influence of brilliant and temperamental leaders, the league makes progress look a lot like an explosion.
Blue wants knowledge and refinement. Red wants inspiration, immediacy, and spectacular results. Izzet is where careful planning and creative improvisation meet—sometimes productively, sometimes in a crater.
In gameplay, blue-red often rewards casting instants and sorceries, copying spells, manipulating cards, and assembling artifact interactions. An Izzet deck might pass a turn with mana open, then chain several spells at once. It isn’t always fast, but the payoff turns can be spectacular.
Golgari Swarm: everything dies, everything feeds something
Colors: black–green. Golgari controls decay and renewal in Ravnica’s undercity. Its members tend fungi, recycle waste, and command undead. That makes the guild vital to a city that would otherwise drown in its own refuse, even if the work is rarely honored.
Green accepts death as part of the natural cycle; black sees opportunity in what others discard. Golgari thus treats the graveyard as a second resource zone rather than merely a record of losses.
On cards, the guild uses self-mill, creature recursion, sacrifice value, death triggers, and resource recovery. A Golgari player isn’t necessarily upset when a creature dies; the real question is what they get back, and when. If your favorite Magic games involve turning a messy graveyard into an advantage, you’re probably already thinking like the Swarm.
Boros Legion: justice at marching speed
Colors: red–white. Boros is Ravnica’s military force, distinguished by soldiers, angels, discipline, and a conviction that the right cause deserves direct action. That moral certainty can be heroic, but it can also make compromise difficult.
White supplies organization and loyalty; red adds conviction and urgency. The resulting guild favors direct confrontation with a clear sense of purpose.
Boros decks commonly attack with multiple creatures, benefit from coordinated combat, and use efficient tricks or damage effects to finish the job. Its creature-heavy identity means sequencing is crucial: when the deck needs several creatures to attack together, removal of just one key piece can matter a great deal.
For casual deckbuilding, Boros is a useful contrast to Azorius: both include white’s sense of order, but the red half prefers to act now while blue is still drafting procedures.
Simic Combine: adaptation without a natural stopping point
Colors: green–blue. The Simic aim to preserve and adapt nature in an artificial metropolis, but biological improvement can become an obsession. The guild experiments with new forms of life and asks what organisms could be if they were no longer constrained by ordinary evolution.
Green gives Simic its biological foundations; blue brings directed experimentation and the desire to optimize. Mechanically, those colors often create more mana, draw more cards, and grow creatures with counters or other improvements.
Simic is a natural choice for players who enjoy planning several turns ahead. Once its engines begin working, a Simic board can grow rapidly. The challenge is not always generating resources; it’s deciding how to convert those resources into a real win before the rest of the table responds.
What is the Guildpact, and why does it matter?
Ravnica’s guilds don’t coexist because they like one another. Their relationship is defined by the Guildpact, a magical and political arrangement intended to maintain a tense structure of power among the guilds. It is part of the explanation for why the city has not simply collapsed under its factions’ competing agendas.
The Guildpact’s form and enforcement change over Ravnica’s many stories. It is therefore easier to understand as a recurring central institution than to treat every old card flavor text as if it described the current state of the plane. Characters such as Jace Beleren and Niv-Mizzet have played important roles in that evolving story. If you’re diving into an older Ravnica set, look at when its story takes place rather than assuming all the guilds are led by the same figures in every era.
The guilds also help explain the city’s apparent contradictions. The Golgari clean and recycle, the Izzet build, the Azorius regulate, and the Boros enforce. Even guilds that seem antagonistic still provide functions the city depends on. Every faction wants more influence, but none can easily replace the whole network.
How guild identity translates into Commander and casual decks
The ten guilds are the same ten two-color combinations that players use to describe Magic decks. Choosing one tells you which colors are allowed by your commander’s color identity, but it does not force you to use guild-themed cards. Your Azorius commander could care about artifacts rather than detaining opponents; your Rakdos deck could be a slower graveyard engine.
For a themed deck, start with three questions:
- Which part of the guild fantasy interests me? Golgari recursion, Izzet spell experiments, and Selesnya creature communities are distinct plans.
- Which game pieces make that fantasy functional? Include mana, card draw, removal, and ways to finish—not just lore references.
- Is the deck built around actual card abilities? A guild’s personality helps choose a direction but doesn’t replace reading card text.
Mana bases offer an easy flavor connection. The ten Ravnica “shock lands” and guild Signets pair mechanical usefulness with setting identity. Our guide to MTG tri-lands and mana-base choices explores another way of planning colored mana. For players building a Commander collection, how to balance your ramp package can help prevent a beautiful guild deck from failing to cast spells.
FAQs
Are there exactly ten Ravnica guilds?
Yes. Each of Magic’s ten possible pairs of two distinct colors has a corresponding major Ravnica guild. The city contains many other groups and citizens, but the ten guilds are its defining institutions.
Which guild is the good one?
None is written as an uncomplicated moral winner. Each guild provides a compelling justification for its work and has reasons outsiders fear or criticize it. That’s a large part of what makes Ravnica interesting.
Are all green-blue decks Simic decks?
“Simic” is common shorthand for green-blue decks, but a green-blue deck doesn’t need to contain any Ravnica cards or follow Simic lore. The nickname refers to the color combination.
Are Ravnica shock lands tied to specific guilds?
Yes. The shock land cycle supplies the relevant pair of colors and is strongly associated with Ravnica’s guild identities. A land such as Steam Vents represents the blue-red pair commonly called Izzet.
The takeaway
Ravnica works because its ten guilds are different answers to the same question: how should a city live? Their mana combinations make those answers playable. Pick a guild for its story, use its color identity to guide a coherent deck, and remember that the most compelling Ravnica characters are often the ones who complicate their own guild’s ideals.
