Right now you don't have any pos 1 carry ninjas (like Kushina would be) so your best bet is to do an offensive oriented setup on your main character and put them in pos 1 so they can be your primary round 2 main attacker. This is what I'd suggest:

You want to use S-Naruto immediately in round 1 to try to slow down your opponents. Having your opponent under Slow will help a lot if they're not immune, especially for a newer player like you who might not have as high of initiative. In Naruto's mystery description it says Slow only lasts until the end of the round but I'm pretty sure I've seen it carry over into round 2 (this might actually be a secondary slow that was applied to the opponent from Naruto's passive and it might have something to do with turn counting? You can read more about turn counting in the comments of this post: https://forum-narutoen.oasgames.com/page/show-post-24555-1.html). But basically, if your opponent is still under Slow in round 2, even if they would normally outspeed, you you'll be able to attack first.

Also in round 1, you should use Iruka. His mystery can be used for interruption, but in this case I'd suggest you instead use the other form of his mystery that makes one of your ninja immune to debuffs for 2 rounds and gives them an extra standard attack. Your main isn't naturally immune to debuffs but I'd suggest you use this on him so he can be.

Guy is there for the attack boost and the life leech. Lightning main also lives this life leech so you should be getting a good amount of health back when you do Taijutsu damage.

Hope this helps!
