Kage treasure. (but i'd really suggest saving for the combined jinchuriki/get roshi now with 210 scrolls)

Barrier is really important right now, along with the special effects they provide (e.g Mei's poison every round), and Sage Naruto will come eventually, it's just a matter of when. He's not exactly the best meta at the moment imo, but will probably more important in the jinchuriki meta.

It took me around 120 pulls to get him though, I think you're better off betting with Kage treasure and if you have to, switch over to light main if you do get light blitz teams.
