You should try to get Asura Naruto as a 20k ninja since he is really good. However if your willing to wait for Edo itachi he's supposed to counter Naruto. But we won't really know till we get him. I'd honestly say go for jonin minato rn because he is cheap and once you have bond mystery he is broken. As long as you have good power with him he will not disappoint and can even beat asura teams of similar power.

Wouldn't his Mystery put naruto to sleep since it cancels any buff? I would think that includes his immunity, correct me if i'm wrong.Also he is good for reflecting naruto's chase every round.So getting that immobile from naruto is pretty much impossible from him using mystery first.

Oh, alright I suppose you're right then, he wouldn't be able to sleep him

A list of some good pos1 ninjas right now:

Angel of God Konan (around 20k)

Edo Hiruzen (around 20k)

Jonin Minato (with bond mystery) (around 10-12k)

(Six Paths) Naruto (around 20k)

(Rinne Sharingan) Sasuke (around 20k)

Edo Deidera (around 16k)

Kushina (Habanero) (around 10-12k)

Shisui (his price changes drastically depending on the event, but c*so get for 200 if you're lucky in rng events)

Water main is also good with shark bombing but you will need a ninja that cancels all buffs as pos2 to make it work at its best. I might have missed some but those are the ones that generally come to mind in this meta

Yes they are all obtainable with both cps and ingots.
