Eternal Decks is a fully cooperative game where players are trying to complete the stage objectives before any one player cannot take an action. Players start the game with 5 cards in their deck, but will quickly look to acquire more cards from the various Eternals (characters within the game) who each have their own unique 8 card deck. On your turn, you must perform one action: Play a card (on the field, on the river, or use an ability) Generate a jewel Give a card to a teammate There are restrictions when playing a card. All 3 rows in the field cannot have cards of the same color or same number next to each other. Additional restrictions are applied to a row based on the stage you are playing. Jewels are used to negate the negative effects brought on by the Eternals. There are 6 stages currently in the game. The various stages will have you collect points, survive a ghost town, navigate a labyrinth, defeat a boss, and more to win the game!
