Madara will be atleast 1000 seal scrolls in gnw treasure just like ay and sasuke sussano, I would suggest you skip cloud treasure and start saving scrolls from gnw and other events in 6-7 months you can save 500-600 seals scrolls if you farm them from every event which will give you 80% of what you need for madara. Also in gnw treasure madara has 50/50 of being pulled because of kurama mode naruto (kurama mode naruto is pretty bad compared to madara right now in cn)

that's probably a * manga, I can tell from the art style
