ok so if you see current meta neither madara gnw or itachi kimono can stand up to any current meta ninjas like Minato, kushina, kakashi etc etc so I'd stuggest go for them instead of madara gnw (different story if you have them) as for itachi kimino na because he got a bug sometimes his barrier will crash the game that's why not many players uses him actually i haven't seen in much it's really rare to see him so i suggest go for kimi instead of him would be nice if you skip this week's fuko and get ninjas which are way better then him and even in great plates there's only sasuke rinne(in packs) expect him others are support ninjas so this week isn't that good for spending

best choice will be go for kushina or kakuzu as a f2p since they can pretty much solo
