I saved 35k cupons for great paltes to get ninjas, power, seal scrolls and the big prize for 3500 keys used, ay and now they nerfed te event. I realy hope that next time will comoe with some shisui frags or idk... now it gives only 1 frags for minato and masked man and 2 frags for kakashi. Last time you got 2 frags for masked man and shisui and 4 for kushina... I really don't like this nerfs... like they did with with fuku and with the 30k rebate and no ninja
