Overview
KeyForge is a card game designed by Richard Garfield and published by Ghost Galaxy. It was released in 2018 and was originally published by Fantasy Flight Games.
Gameplay
KeyForge is a two-player game, with each player using a single deck of cards to play creatures, artifacts, actions, and upgrades. The game aims to gather enough Æmber (pronounced "amber") to forge three keys before the opponent does the same. Creatures can collect Æmber and fight one another, while artifacts provide unique effects. Actions are used and discarded, and upgrades are attached to creatures to improve their abilities.
Each card in KeyForge is associated with a House, with each deck containing cards from three Houses. At the beginning of each player's turn, that player declares a House – they may then only play, use, or discard cards belonging to that House. Unlike similar card games such as Magic: The Gathering and Android: Netrunner, cards do not typically require a cost to be paid such as the expenditure of mana or credits. Instead, a player may play and use as many cards on their turn as they wish, provided the cards belong to the declared House.
Each deck features a unique card back with the name of an Archon. Decks are intended not to be modified after purchase. This is intended to reduce card trading and selling so that "net decking" (the process of researching and recreating more powerful decks) is made more difficult or impossible.
