Eternal is a free-to-play online collectible card video game developed and published by Dire Wolf Digital.

[5] The game features cross-platform play, allowing players to use any of the supported platforms to compete against each other.

The game features several modes of play, including ranked matches and single-player campaigns.

Shiftstone is also acquired after opening each card pack, from completing certain achievements or from faction rank up rewards.

[13] Alternate names for tri-color factions are: Creation for FTJ, Instinct for FTP, Destruction for FTS, Honor for FJP, Ambition FJS, Menace for FPS, Tradition for TJP, Vision for TJS, Knowledge for TPS, Purpose for JPS.

The Empty Throne is the free base campaign that serves as a tutorial to introduce new players to the game that was released on November 19, 2016.

The Empty Throne is also the name for the first full set that was released on November 19, 2016, that features 413 cards.

Players take on the role of an apprentice to Jekk, the Bounty Hunter, who guides them on a series of 16 single-player missions.

The set features 252 cards, new faction pairs and new mechanics such as Spark that adds an additional effect if the opponent has been damaged this turn, Revenge that allows a dead minion to be shuffled into a player's deck and if drawn is put into play and Warp that allows the top card of the deck to played as if it was in the player's hand.

Players take on the role of homesteader Horus Traver, as he is guided towards his destiny as a Stranger by Azindel.

It tells the story of Valkyrie Captain Icaria's rebellion against Lord Commander Rolant, so its story begins in the past before the events of The Empty Throne campaign and then continues until Rolant is ultimately killed.

The set features 279 cards and new mechanics like Inspire that does something when you draw a minion, Spellcraft, that lets you do an additional effect if you spend more power, Berserk that lets minions attack twice and adds merchants that only swap a card in hand with one from the market, which is similar to a sideboard.

It follows Vara in her pursuit of Azindel, who stole her memories, and the discovery that Caiphus, her father, is still alive.

The story follows Svetya as she leads the remains of her royal guard along with Milos and his rebels to take back her homeland, Kosul, from Yushkov.

[40] Throne, Casual and Expedition are PvP modes, where players use constructed 75-card decks using the cards in their collection.

Throne mode (previously called Ranked) is a monthly leaderboard ladder divided into five brackets through which players climb: Bronze, Silver, Gold, Diamond and Master, gaining rating points with every win and losing points with each loss.

[42] In the Draft (PvP) and Forge (PvE) modes, players build a new deck from a limited pool of cards presented to them.

Both modes require in-game gold or gems (from microtransactions with real money) to enter.

[45] Eternal features many puzzles that focus on different game mechanics such as Deadly (kill any unit damaged) and Aegis (negates one effect from the player's opponent).

Since transitioning from closed to open beta, Eternal has hosted in-game limited time PvP events[46] with their own unique twists.

[50] Eternal has monthly tournament events that have cash prizes and will culminate in a $100,000 World Championship in early 2020.

[51] Rewards in Eternal take the form of individual cards, gold and packs.

Rewards come in treasure chests of varying rarity: Bronze, Silver, Gold and Diamond.

Rewards are earned after every ranked, casual and expedition mode win, and upon completion of daily quests, drafts, events, forges and gauntlets.

[52] In addition, watching Twitch streamers playing Eternal can reward drops that include cards, packs and draft mode tickets.

[53] Eternal was announced in January 2016 at PAX South,[54] and began a closed beta that April.

[57] The game was developed at Dire Wolf Digital by a team that has included Magic: The Gathering Hall of Fame players Luis Scott-Vargas[58] and Patrick Chapin as well as other Magic: The Gathering professional players including Conley Woods, Andrew Baeckstrom, Patrick Sullivan and Josh Utter-Leyton.

[65] PC Gamer praised the use of 'instant' cards that can be played during your opponent's turn while making things streamlined and quick; the reviewer says the game had his favorite draft mode in digital gaming that creates a deck from four card packs that the player keeps after the mode is finished.
