Hello~

It's completely random, others got it for their first 60 pulls, others got it with their 120th pull, while others got him even more than that. :)

You c*e him together with the Jinchurikis to proc their "hit-combo" chase. Also, I used to use Sage Naruto along with Kazekage Gaara, Killer Bee, and Wind Main.

There's also a thread in the strategy section asking for Sage Naruto lineups too. Here are some:

Or if you'd like, you can post one here and let other players help you create a good team for you
