I'm a one star rating because without any star I cannot provide my comments. The main thing is I don't know why the MK mobile introduced the tower battles the boss characters they are setting in towers are irrelevant and you cannot beat them until unless you have any fusion X diamond cards. And if you tried so much time on beating the boss they the reword you will get some nasty rewards. if you open any pack for Diamon cards you don't get them. If you want to waste your time you can play.
