I had to give this game 2 star before you play and spend money. Understand that you have to use a meta team for pvp and somewhat pve. Lots of units are useless in pvp zenkai doesn't do justice for everyone so be careful with that. Ultra banners you need to be very lucky on them or do care about wasting 75k summons and not getting the one Ultra character. They used to be free to play but sadly not anymore. Nano was right the Ultra on banners will ruin this game
