Hey guys!

Note that he gets a mystery skill improvement at 4 stars, 1 more attack and immunity is amazing especially since you can basically use his mystery every round.

From his other skills there are decent ones, especially considering that he is a f2p ninja

Having acupuncture chase, having a scaling passive, un-dodgeable attacks

With that said I didn't really make many full f2p teams, if you want to make such teams I'd recommend using your main as pos1 , shira pos2 and then sasuke 3 stars/guy / wb asuma and such ninjas to buff them also.

1. Earth Main

This team can of course also use 6 paths Naruto

Quite versatile, safe and has decent damage

2. Earth Main 2

This is a risky full buff blitz team, and of course works much better with Shira being 4 stars

Using Kazekage Gaara as barrier here is also an option, or if you don't want a barrier then use Guy for example

3. Fire Main

A typical jonin minato-5 kage madara team, we know that one is also quite decent

4. Fire Main 2

This one is a bit more on f2p side

5. Lightning Main

Also a bit more toward f2p side of teams, this kind of team works especially good in arena

Optional warrior killing intent talent instead of anbu tactics

6. Wind Main

A bit of cancer-ish damage team, quite safe also except from direct high damage such as Edo Hiruzen

Hopefully you can remove buffs from your enemy in round 1 with Wind Main, after that easy :p
