This is really a good game, easy to play and fun. The graphic is really cool and the gameplay is good. But if you try to play ranked duels pvp game without spending money to earn good cards, please don't, or you will end up losing and losing. The matching system is really bad, it is not fair. You'll be match with players that have stronger deck and higher rank than you. Unless you have strong deck, which you can't get just only from completing mission but buy with real money, you can't win
