The game has new content twice a month so you will always have something to work on. I have been playing for a few months now and its a great game to play with your friends. The only downside is development and deck building. In order to get the best cards and buildings are going through jewels. If you are patient, a free player has to wait months to get the amount of jewels to buy and upgrade buildings. Other than that, UR cards are hard to get for beginners. I so far have only one at lvl 72. Besides that, its a fun game.
I am not trying to advertise but if you are in an alliance with random people or your friends, I recommend downloading an app called Line because its a great way to communicate with your alliance members. That way, you can tell them when a Faw or Law is out and know who is attending an alliance battle
