Mabinogi Duel is a portrait mode (optional landscape mode) TCG developed devCAT featuring characters from the original Mabinogi Fantasy Life with a touch of Vindictus artwork. Not being able to read Korean at all, I was somewhat confused with the game system. Thankfully, the tutorial walks players through the basics and advance features of the game. The game runs at 60FPS or something crazy because it's extremely smooth. The developers did a nice job with the UI, it's unique compared to most TCG currently out in the market. Mabinogi Duel's element system gives off a Magic The Gathering vibe.
I've stopped playing the Korean version and started playing the English version! It looks like they added the latest PvP Arena in this version where you can play against other players real-time. In short, there are a lot more PvP Arena Options such as real-time PvP Arena with other players, newbie and veteran Arena vs player ghosts, draft arena vs player ghosts, practice arena, duel arena with a friend, and more! Players can earn free cards from login bonuses, daily missions, and more. The game is pretty good and enjoyable that I didn't mind starting all over again in the English version.
