"Don't try to change the Crucible to fit your needs. Let it change you."

Enter a world where anything is possible in KeyForge! In the center of the universe hangs the Crucible, an artificial world built from the pieces of countless planets. Here, in the world’s first Unique Deck Game, created by legendary designer Richard Garfield, two players step into the roles of mighty Archons, racing to forge keys that unlock the Crucible’s hidden Vaults.

Leading their diverse teams, filled with followers from three of the Crucible’s great Houses, the Archons must gather Æmber, stave off their opponent’s progress, and ultimately be the first to open a Vault and gain its incredible knowledge. With a vast array of creatures, artifacts, and abilities and over 104 quadrillion possible decks, every deck is completely one-of-a-kind, and no two battles will ever be the same!

Beyond its groundbreaking mechanics as the world’s first Unique Deck Game, KeyForge also offers an incredible array of options for players with equally-matched standalone sets. Every set of KeyForge, whether it be Call of the ArchonsAge of Ascension, or any other, is a companion to each other set, not a replacement or a sequel. You do not need to start with one set in order to reach another, and you do not need to switch to the latest Archon Decks in order to remain competitive. Rather, you are invited to continue your exploration of the Crucible with new cardpools that feature incredible new creatures, artifacts, keywords, and sometimes even new Houses! It’s your game, and you can play it your way.

A World of Infinite Possibilities

In KeyForge, you become an Archon, one of the only native inhabitants of the Crucible. This world was built for your kind by the mischievous and enigmatic Architects, who cobbled together pieces of every planet in the galaxy, bringing with them an eclectic variety of creatures, vegetation, cultures, and technology from across the stars!

Hailed by some as a god, you now seek to understand the secrets of the planet on which you live. This knowledge is held in countless hidden Vaults, which you must find and unlock using keys forged of Æmber, a precious substance that runs throughout the Crucible. To this end, you have gathered a team drawn from three of the Crucible’s seven great Houses. But you are not the only one seeking this knowledge and the power that comes with it—rival Archons across the planet all seek the same goal, and when two Archons meet at a Vault, conflict is inevitable.

Chaotic Clashes

When two Archons meet in combat, you must be ready to react and learn on the fly, using every tool at your disposal to counter the tricks your rival has up their sleeves. Within each House, you will find four types of cards: actions, artifacts, creatures, and upgrades, based on what these Houses brought from their homeworld or created after arriving on the Crucible. Over a series of turns, you will use these creatures and cards to collect precious Æmber, battle your opponent, and ultimately forge enough keys to unlock the Architects’ Vault!

At the start of your turn, you will choose one of the three Houses within your deck and activate it. Once you have declared your active House, you may only play and use cards from that House, so be sure to choose wisely. Though you only can activate one House per turn, you're free to use those cards as you please: no cards have a cost in KeyForge, so you can use your active House to run wild, playing and using cards without limit. At the end of your turn, you will draw back up to a full hand of six cards, so it may be best to play as many cards from your hand as possible. Then again, you may want to hold your best tricks back so you can get their full impact at the opportune moment! And that's just the start of the tactical choices to make in every turn of KeyForge.

When you play creatures from your hand, you must build your team outward from the center, playing cards to the left and right of your creatures already on the field. But when you strike, you may attack with any of your creatures, regardless of their placement in your ranks. Once creatures are locked in combat, they match strength against strength, with each side dealing and taking damage.

For example, the Staunch Knight, aligned with Radiant Argus the Supreme, attacks Valdr, who follows Miss "Onyx" Censorius, while both are on a flank. The Staunch Knight's power of four, combined with his bonus two power for being on a flank would make him strong enough to end Valdr! Still, Valdr's six power would also be enough to destroy the Staunch Knight in return. Cards enter and leave play quickly in a game of KeyForge, with your allies entering and leaving play at a moment’s notice. You must choose carefully how and when to use your cards—you never know when your opponent will wipe your creatures away, and you must be ready to come back with a new plan, lest you suffer the agony of defeat.

But beyond battle, the heart of KeyForge, the purpose for your Archon's presence, is the Æmber itself. While you must keep your enemy from gaining the advantage, you must take care to never lose sight of your goal: reaping and gathering as much Æmber as you can. While the act of reaping exhausts a creature and prevents it from battling for the turn, it also earns Æmber for your pool.

If you have six Æmber collected at the end of your turn, you must declare “Check!” as a warning to your opponent. Then, if your opponent fails to foil your plans and you still have six Æmber at the start of your next turn, you immediately forge a key, moving one step closer to opening the Vault and the knowledge within. The first Archon to forge three keys is the winner!

Houses of the Crucible

Within each Archon Deck, you will find members of three of the Crucible's great Houses. There are seven Houses to draw from, each with a unique culture, history, and technology that makes them stand out among their peers.


The brawlers of Brobnar are a proud, boisterous people who value strength above all. Ruled only by the physically strongest among them, what they love most is a good fight, and each person is only entitled to what they are able to take and protect.



The empire of Mars is exceptional has remained mostly unchanged since its relocation to the Crucible. Still ruled by the Elders, they continue their biological experiments to create the perfect monster and fight using ray guns and flying saucers to ensure their culture survives.



The angelic knights and crusaders of Sanctum keep their home on the Crucible safe, clean, and pleasant—a rare thing on the planet. Floating on golden wings, these warriors protect the weak, defend the innocent, and destroy all who threaten their order.



The scholars of Logos are the self-proclaimed "foremost" intellectuals of the Crucible. Logotarians often replace parts of their bodies with technology, and while some call their experiments deranged, they know that true understanding is worth more than any one life.



The demonic creatures of Dis are unmatched in cruelty and sheer ruthless. Dwelling in the deep underground of the Crucible, they incorporate Æmber into their minions to help them gather more of the precious substance and more souls.



Shadows is filled with a motley crew of rogues, thieves, con-artists, sometimes-assassins, and general ne'er-do-wells. Known for cleverness and speed, they repurpose what they lift from other Houses to survive.



The varied creatures of Untamed reject civilization, choosing to live in the wilds of the Crucible. Built by blending myriad biomes, this House is loosely organized, but all live true to their nature, whatever it may be.


Saurian Republic

The Saurian Republic is a sixty-five-million-year-old empire. Under the lead of Sauras Rex, first among equals, these brilliant and physically imposing dinos pride themselves on their philosophical debates and technology so advanced that some mistake it for magic.


Grand Star Alliance

The Grand Star Alliance is one of the most inclusive Houses on the Crucible. After the SAV Quantum crash-landed, their scientists and explorers built a small city where their multi-species community continues their mission of exploration, learning, and discovery.



Dwelling deep in the oceans of the Crucible, the Unfathomable is the newest House replacing House of Dis in the rotation of active houses. With a mix of humanoid Aquans and dangerous deep-sea beasts, the Unfathomable can be deadly for unprepared creatures that stray into their domain.


Exploring New Vistas

What sets KeyForge apart from any other game in the world? KeyForge is the first of a new breed of game from Fantasy Flight Games—the Unique Game, and specifically, a Unique Deck Game. Unique Games can take many forms, but what this means for KeyForge is that every deck in existence is utterly unique and different from every other deck.

There is no drafting, deckbuilding, or boosters; every Archon Deck is complete and cannot be changed. This is part of the challenge—using only the tools at your disposal, you must best your opponent in a game of tactics. Power does not come from a single card, but rather in how the cards within a deck play off one another, just like how a team is defined by how players interact rather than by a single star.

You begin your adventures with the KeyForge Two-Player Starter Set, which includes everything two players need to throw themselves into the world of the Crucible. As you can see below, you'll find all the tokens two players need to play, two poster playmats, and two Archon Decks that remain a mystery to the world until you open them up and peer inside.

Once you have mastered the KeyForge Two-Player Starter Set, the next step is to expand your collection of unique Archon Decks. These decks each offer a full play experience, complete with a distinct name, Archon design, and scan code that allows you to track your deck in the KeyForge companion app and website. Once you jump into the world of the Crucible, you can take your gaming to the next level by joining the community in the Master Vault at Here, you can record your Archon Decks from every KeyForge set, track their performance at events, follow the progress of other Archons across the globe, and stay updated on tournaments and event news from the Fantasy Flight Games Organized Play team. The Master Vault will continue to grow and evolve alongside the game and the community, so be sure to stay tuned to see what the clever Architects have in store!

Accept the Challenge

A new world of limitless possibilities stands before you, filled with ancient secrets and newfound friends. How you will help shape this planet and find your place among its many inhabitants is up to you. Are you ready to embrace new challenges and explore a world beyond anything you have come to expect? Gather your allies and prepare for a new adventure in a new world!
