I've been playing this game for years it was very addictive and fun until I started to notice the p2w part of the game. 90% of the game is to get better monsters but when the best monsters are in the battlepass or cost money it seems if you pay money you will become "better". The game really tries to make you pay so alot of the shop is monster deals, limited chests, or bundles. All things aside it is possible to get it normally but it takes hours apon hours to do without in app purchases.
