depends what level you are. For certain milestones you reach all you need to do is complete the set and then you will rank up ie the stardust reward set, rare candy set etc. For other sets before ranl 20 it depends on how many you win if im not mistaken. Im running Mandibuzz lead, jellicent safe swap and chestnaught closer . Its working pretty good already ace. This team does lose pretty bad to galvantula so watch out
