heads up - this game is one of the most p2w games on the android market. Take heed when decided to play any of Mobage games, all which are extremely pay to win. You will hit frequent brick walls. forget about getting any good 6*+ cards unless u spend hundreds. forget about doing events if u dont spend some serious dough because u will never be on rankings. If you played blood brothers then u should already know what kind of events this game will hold.
