Play KeyForge for Free

Four Mass Mutation Decks Are Now Available to Print and Play


For most gamers in the United States and many countries around the world, social isolation has limited our access to regular tabletop gaming. Even though upcoming FFG releases have been delayed, we still wanted to share some of our most exciting upcoming products with you—starting with the Mass Mutation set for KeyForge!

If you’ve never played KeyForge, this Unique Deck Game from renowned game designer Richard Garfield puts you in a head-to-head race to summon your creatures, gather the mysterious substance known as æmber, and forge three keys before your opponent. Unlike many other card games, every deck in KeyForge is algorithmically generated, drawing from a common cardpool to offer a unique, fixed deck that’s unlike any other deck in existence, with card combinations and strategies that only you can master.

Mass Mutation is the newest set of Archon Decks for KeyForge, introducing the mutative effects of dark æmber to the Crucible, along with billions upon billions more completely unique decks. Drawing from a cardpool of 422 cards, Mass Mutation brings over 250 brand-new cards to your decks. You’ll find strange new versions of familiar characters, massive creatures that stretch across more than one card, and the triumphant return of House Sanctum.

Whether you’re completely new to KeyForge or you’re eagerly awaiting the release of Mass Mutation, you can get your first taste of the new set for free today!

The Mutation Begins

Fantasy Flight Games is proud to present four new KeyForge Archon Decks, each drawn from the Mass Mutation set and now available for you to download and start playing! Important note: All files are the property of Fantasy Flight Games and may only be used for personal and private purposes. All forms of commercial operation are excluded.

In conjunction with the deck PDFs above, you can find the Mass Mutation quickstart rules here (2.9 MB). If you’re a KeyForge veteran, that should be all you need to start playing, but if you’re new to the game, you’ll want to grab a few proxy tokens. You can print off our token sheet ( Side A , 23 MB – Side B , 23 MB) for paper tokens, or simply grab some common household items!

Keys: The objective of the game in KeyForge is to be the first player to forge three keys—and as such, you’ll need to proxy three keys per player! These keys can be anything that has two distinct sides to represent unforged or forged keys, but we recommend using coins as a proxy that’s easily available, small in size, and has two distinct sides.

Damage and Æmber: The other common game elements that you’ll want to track with proxy tokens are damage and æmber. You can use any kind of small token to track damage and æmber, and we suggest using dice (six-sided or otherwise) as a space-efficient way to keep track of how much damage has been taken by a creature or how much æmber you’ve collected.

Status Effects: Some cards can cause status tokens, such as stun, ward, or enrage. You shouldn’t need many of these tokens—just a handful of unique tokens from another game in your collection that you can use as stand-ins should be sufficient!

We hope that you enjoy playing with these Mass Mutation decks and that they bring some more fun and entertainment to your social isolation! We’re looking forward to releasing the full Mass Mutation set later in 2020.
