Hello,
I have stumbled across a lineup as earth main that has allowed me to BREEZE through SA Normal. It has also proven to work on Easy mode which i find more difficult due to Haku going kage mode and nuking the team to 1hp. The linup is as follows

POWER - 14916

LINEUP
X - X - X
X - Iruka - Hinata
X - Lee - Earth Main
Currently you can get Eight Gates Lee for free during this christmas event, do it if you have not as he is the star of this lineup.
If you do not have Eight Gates Lee you can try with normal Lee. I have not so i cannot confirm if it will be as effective.

TALENTS
2 - Earth Style: Super Stone Fist
3 - Earth Style: Petryfing Jutsu
3 - Earth Style: Stone Fist Jutsu Fall
2 - Pose of Duel
2 - Steel Body
SUMMON
Ninja Dog Shiba

You can

WAVE 1: Zetsu Archers
ROUND 1: Use Hinatas Mystery immediatly, this will negate the damage from round 1. It is likely 1 of the Zetsus will be slain, another badly wounded, or 2 will be badly wounded.

ROUND 2: Use Lee`s mystery right away. You will recieve at most 1 chakra arrow attack, but it wont get through the shield typically, doing little damage. Lee will then finish off the two weakend zetsu, and then auto attack will mop up whats left.

WAVE 2: Hidan & Kakuzo
Round 1: Use Hinatas myster to negate damage and let Lee just run rampant.

Round 2: Quickly use Irukas mystery to interupt Hidan, and just auto them down, using lees myster right away as well.

Round 3: Let your team auto attack them down, they should fall in round 3 and you will have taken minimal damage. Hinata may be injured but no worries, she is expendable.

WAVE 3: Hidan & PainAnimal Path

Round 1: IMMEDIATLY use earth mains mystery on Pain to combo into Hinatas accupuncture to stop her tag mystery. IF lee`s mystery is up, use it.

Round 2: Use Irukas mystery to iterupt Hidan and let the auto attacks do the work

Round 3: At this point Hidan may be down, if not he should be low health along with Pain and Lee`s mystery allong with auto will finish everything off.

NOTES
I have only ever lost Hinata, but Lee is the real star here. Being buffed by Iruka and earth main along with the shields allows him to take little to no damage and pound everything for big damage with his autos and mystery.

Hopefully this helps you folks out. I dont know if this works with ther mains, a the shields from Earth and Iruka are what really lets you get through this on nearly full HP on most memebers. If anyone tries this with other mains let me know how it works.
