Eternal Card Game frames its strategy around a fantasy clash of six-guns and sorcery, with deck construction and tactical combat at its core. The store description highlights fast-spells and counterplay, suggesting that players must weigh when to act as well as which cards to include. It also describes deckbuilding without restrictions on which cards can be combined, leaving room for varied approaches.
The game offers several ways to build and test a deck. In Draft, players assemble a deck from cards passed by other players and keep the cards they draft; Sealed League instead begins with packs and develops into a month-long competition. Constructed formats feature leaderboards, while tournaments and events provide other competitive settings. Practice Mode is presented as a place for experimental combinations, and story-driven campaigns add player-versus-environment battles and new cards.
Solo play also has dedicated options: Forge asks players to choose from groups of cards before taking on AI opponents, while Gauntlet tests a constructed deck against AI and boss powers. The listing additionally identifies single-player, multiplayer, online PvP, and cross-platform play, with accounts and collections able to travel across supported platforms.
