I stumbled upon it and got curious, but I don’t understand how it works. It seems like it’s not a typical social casino, but rather, it has different mechanics. I’ve read that it has something to do with digital cards and duels, but I have no idea how it all fits together or how to start playing. Has anyone figured it out yet? Can someone explain it to me or point me to a good beginner's guide so I don’t have to spend an hour figuring it out on my own?
