MOBA Duels is a 1 vs 1 real-time battle card game. You can collect and upgrade dozens of different hero cards, every hero comes with 4 unique skills, which are casted automatically in battle (the sequence of skill casting varies for each hero and battle situation). Since it is a 1 vs 1 MOBA game (developer already confirmed a future 2 vs 2), the battle rules are pretty easy with a goal of destroying the opponent base. Summoning hero card requires a cost that generates automatically during the battle. There are different rarity of the hero cards - Classic, Epic and Legendary. You can level up them and apply skill points to make them stronger. You will need to form your own deck with the unique heroes, so the key to getting a victory here is the strategic combination of cards. There are some skill cards and soldier cards to help you out too. By winning battles, you can get chests and unlock hero cards. MOBA Duels also features a ranking system, your rank decides the map you will be battling. In short, the game is basically a horizontal version of Clash Royale but with enhanced features like upgrading Hero skills.
