Indeed this is the first time i see such bad fuku rewards. Its not even about free/fireworks ninjas, its about that they aren't worth their price here at all. Would be better to see some naruto sosp/kisame/madaras/etc there. The best way would probably be to mix meta (sosp/kisame), old meta (kushina/jonin minato/....) and fun (hinata bride etc) ninjas in 1 pack to choose from
