TLDR: the ten guilds are two-color philosophies with uniforms
Ravnica’s ten guilds represent Magic’s ten possible two-color combinations. Each guild takes the values, methods, and contradictions of two colors and turns them into a civic institution: lawmakers, spies, entertainers, raiders, soldiers, scientists, and several organizations that should probably not be trusted with public funding.
The key is that a guild is one interpretation of its color pair, not the only interpretation. Blue-red can mean Izzet-style reckless invention, but it can also support spell-copying, tempo, artifacts, or a Commander deck with no Ravnican flavor at all. Use the guild names as convenient color-pair vocabulary, then let the cards and deck plan decide what those colors actually do.
Why Ravnica defines Magic’s two-color pairs
The original Ravnica: City of Guilds arrived in October 2005. Its three-set block distributed the guilds in a four-three-three structure and gave every guild its own mechanic, visual identity, civic role, leadership, and creature mix. Wizards has described the block as an important step toward supporting all ten pairs—including the five enemy-color combinations—more evenly in Magic design.
On the official Ravnica plane guide, Wizards describes Ravnica as a city-world dominated by ten guilds whose cultures and functions grow from their respective colors of mana. That structure made the color pie tangible. Instead of merely saying white-blue values order and knowledge, Ravnica gives those ideas offices, laws, arrest powers, and enough paperwork to defeat an Eldrazi through administrative delay.
The result became Magic’s default vocabulary for two-color decks. Players commonly call a green-blue deck “Simic” or a black-red deck “Rakdos” even when the list contains no Ravnica cards. For the broader naming system—including shards, wedges, and four-color combinations—see our guide to Magic color combinations.
All ten Ravnica guild color pairs at a glance
| Guild | Color pair | Philosophical bargain | Common deck signal |
|---|---|---|---|
| Azorius | White-blue | Order improved by knowledge | Control, flyers, tempo |
| Dimir | Blue-black | Knowledge used as power | Evasion, graveyards, disruption |
| Rakdos | Black-red | Freedom without restraint | Aggression, sacrifice, spectacle |
| Gruul | Red-green | Instinct against imposed civilization | Large threats, combat, ramp |
| Selesnya | Green-white | Community through shared purpose | Tokens, counters, go-wide boards |
| Orzhov | White-black | Hierarchy serving ambition | Life drain, sacrifice, recursion |
| Izzet | Blue-red | Curiosity released through action | Instants, sorceries, artifacts |
| Golgari | Black-green | Life and death as one resource cycle | Graveyards, recursion, attrition |
| Boros | Red-white | Passion disciplined into collective action | Combat, equipment, go-wide pressure |
| Simic | Green-blue | Natural potential refined through adaptation | Counters, ramp, card advantage |
Azorius, Dimir, Rakdos, Gruul, and Selesnya are the five allied-color guilds. Orzhov, Izzet, Golgari, Boros, and Simic represent the five enemy pairs. “Enemy” describes their positions and philosophical tensions in the color pie; it does not mean those combinations are inherently weaker or less cooperative.
The allied-color guilds
Azorius Senate: white-blue
White wants order, rules, and collective stability. Blue wants knowledge, refinement, and carefully constructed solutions. Azorius combines them into government by procedure: society can be improved if the correct system is designed and everyone follows it.
In deckbuilding, that often becomes control, defensive creatures, flying threats, tapping effects, or tempo. The philosophical weakness is paralysis. A plan can become so committed to preventing mistakes that it forgets to win the game. If your Azorius deck has seventeen answers and one exhausted 2/2 as its victory condition, the Senate has completed its work.
House Dimir: blue-black
Blue seeks information and mastery; black seeks agency and advantage. Dimir treats secrets as leverage. Its ideal tool is precise, deniable, and already in place before anyone notices the problem.
Dimir decks commonly use evasion, card selection, graveyard interaction, milling, theft, or hand disruption. The useful deckbuilding lesson is to connect the disruption to a finish. Knowing every card in an opponent’s hand is clever; ending the game before they draw out of the problem is cleverer.
Cult of Rakdos: black-red
Black prioritizes personal ambition, while red prizes emotion, freedom, and immediate experience. Rakdos unites them through uninhibited self-expression. On Ravnica, that becomes entertainment mixed with danger and a workplace safety record best left untranslated.
Rakdos gameplay tends toward aggression, sacrifice, discard, direct damage, and rewards for spending life or losing permanents. Its best decks turn apparently negative costs into momentum. Its worst decks sacrifice half the battlefield, produce three mana, and discover that enthusiasm is not card advantage.
Gruul Clans: red-green
Red trusts instinct; green trusts the natural order. Gruul sees imposed civilization as a cage and answers it with personal freedom, physical force, and a return to untamed life.
That philosophy supports ramp, enormous creatures, land synergies, haste, and combat-based removal. Gruul decks are strongest when acceleration produces pressure rather than merely a majestic collection of unused mana. The practical question is not whether the deck can cast a ten-mana creature, but whether doing so changes the game immediately.
Selesnya Conclave: green-white
Green values interdependence and belonging; white values cooperation and social structure. Selesnya sees individual strength as part of a larger living community.
Mechanically, that points toward creature tokens, +1/+1 counters, anthem effects, life gain, and wide battlefields. Selesnya decks need protection or rebuilding tools because committing twenty creatures to the board is a persuasive argument for someone else to cast a sweeper.
The enemy-color guilds
Orzhov Syndicate: white-black
White builds institutions; black uses systems to secure power. Orzhov resolves that tension through hierarchy, obligation, and contracts that somehow remain enforceable after death.
Orzhov decks often drain life, sacrifice creatures, recur permanents, and profit from death triggers. This pair is excellent at turning small exchanges into a long-term advantage. It can also become painfully slow if every card generates value but none creates a decisive route to victory.
Izzet League: blue-red
Blue wants understanding and technical perfection. Red wants inspiration and action now, preferably before the laboratory receives planning permission. Izzet treats experimentation as the bridge between them.
Expect instants, sorceries, spell copying, artifacts, triggered abilities, and explosive turns. A good Izzet deck balances setup with payoff density. Drawing six cards and doubling three spells looks impressive, but only if one of those spells matters.
Golgari Swarm: black-green
Green accepts the cycles of nature, while black refuses to waste any available resource. Golgari therefore treats death as transformation rather than an ending.
Its decks use self-mill, recursion, sacrifice, creature-based value, and graveyard payoffs. The graveyard should advance a concrete plan, not become a second hand containing forty cards the deck cannot retrieve. Golgari is patient, but your pod may be less so.
Boros Legion: red-white
Red supplies passion, courage, and urgency. White directs that energy toward duty and coordinated action. Boros believes emotion can serve a cause rather than merely break furniture.
Boros gameplay favors combat, equipment, tokens, attack triggers, and efficient removal. Its central challenge is sustaining resources after the first assault. Modern Boros decks work best when attacking also draws cards, creates permanents, recurs threats, or otherwise funds the next combat step.
Simic Combine: green-blue
Green values natural potential; blue believes deliberate improvement can unlock something greater. Simic combines growth with adaptation, asking not whether nature should change, but how intelligently it can be guided.
That produces +1/+1 counters, ramp, card draw, creature modification, and scaling threats. Simic’s danger is accumulating resources without selecting a finish. A seven-card hand, twelve lands, and a board of evolving sea monsters should eventually become more than an aquarium with excellent funding.
Mechanics change, but the philosophical core survives
Every visit to Ravnica expresses the guilds through different mechanics. The original block included convoke, dredge, transmute, replicate, haunt, bloodthirst, radiance, forecast, hellbent, and graft. Return to Ravnica and Gatecrash later used mechanics such as detain, overload, unleash, populate, extort, cipher, bloodrush, battalion, and evolve.
Those mechanics are historical implementations, not permanent definitions. Selesnya can still feel communal without convoke, and an Izzet deck does not need replicate to feel experimental. Wizards’ color-pie discussions frame a pair through what the colors share, where they disagree, which goals they pursue, and which methods they accept. The guild is a memorable answer to those questions, not the final answer. Wizards’ original guild design discussion makes that distinction especially useful when thinking beyond one set.
How guild identity helps with deckbuilding
Start with the philosophical bargain, then translate it into game actions. If your deck is Golgari, ask what moving cards through the graveyard accomplishes. If it is Boros, decide what attacking generates besides damage. If it is Azorius, identify how the deck turns control into a finish.
- Choose a primary plan. “Blue-red spells” is a color pair; copying efficient interaction to enable a decisive payoff is a plan.
- Use the guild identity to find complementary effects. Selesnya token production wants payoffs, protection, and recovery—not merely more token makers.
- Respect the pair’s usual weakness. Boros needs sustained cards, Dimir needs a clock, and Simic often needs interaction or a cleaner finish.
- Test packages rather than mascots. A graveyard payoff without enablers or a spellslinger payoff without enough cheap spells is just a decorative guild pin.
Guild names and Commander color identity are related, not identical
In Commander, deck legality follows color identity. That identity includes a card’s colors plus mana symbols in its rules text, and every card in the deck must fit within the commander’s identity. The current Commander rules provide the formal definition.
A white-blue commander therefore permits an Azorius-color deck, but the deck does not need to feature the Azorius Senate. Conversely, a Ravnican character can carry a color identity that determines legality more precisely than its job title or story allegiance. Check the actual card, not the watermark, costume, or suspicious quantity of Senate stationery.
Guild names also help organize mana bases. Ravnica’s ten shock lands map directly to the ten pairs, including Steam Vents for Izzet colors, Stomping Ground for Gruul, and Temple Garden for Selesnya. Wizards highlighted those lands again when announcing Ravnica Remastered, which released on January 12, 2024 and drew from thirteen sets across sixteen years of Ravnica history.
Use philosophy to choose cards, not to trap the deck
The most useful way to understand a guild is as a tension between two colors. One color supplies a goal or value; the other changes the methods available. That tension explains why Orzhov can be communal and exploitative, why Izzet can be methodical and impulsive, and why Simic can respect nature while redesigning it.
For a deeper tour of civic roles, major lore themes, and the guilds as factions, continue with our lore guide to all ten Ravnica guilds. If you are building a deck, stay focused on the mechanical question: what does this pair help you do repeatedly, what weakness must you cover, and how does the deck actually close the game?
Pick the guild whose compromise matches the plan—not merely the one with the best logo. Ravnica gives the color pairs names and personalities. Your cards still have to do the work.
