About this game
Heart Duels
Discover the world of Erisa by joining one of three factions:
Each faction has its own worldview, identity, characters, and story path. Meet faction members, challenge them to ranked duels, earn their cards, and unlock their stories, quests, and world lore.
Collect cards, build your custom deck, master the tactical board, and rise through the ranks to become the King of Duels.
Tactical Card Game Mechanics
Heart Duels is a trading card game where positioning matters as much as the cards you play.
Duels take place on a compact tactical board with front rows, back rows, and special cover lanes. Units have keywords and abilities, while spells and items give you more ways to shape the battle.
Your cards alone do not determine your fate. Skill, tactics, and clever positioning decide who wins.
Master your cards. Control the board. Outthink your opponent.
