There aren’t that many really good collectible card games around, especially those that try not to copy the most famous games in the genre, such as Hearthstone and Magic: The Gathering. Duelyst is one of those games -- it really offers something both new and exciting at the same time.
Of course, it has the fundamental mechanics of a card game -- the deck building, the mana utilization, the battlefield, etc. However, Duelyst has a fantastic visual style that gives this game an exclusive quality. It looks and plays more like a turn-based strategy with CCG elements rather than a pure card-based game.
This makes it a completely unique game that takes a different approach to the whole genre; and worth the time of any fans looking for something slightly different.
