Good evening guys! This is the first time I do a strategy post, but here it is: I finally got a fire main team to beat level 137.

Ok, with this team it's important to place the ninja in the correct order: 1st place Fire Main, 2nd Naruto, then Gaara or Killer Bee. My Naruto had max breakthrough, but I didn't use Multi Shadow Clone Jutsu +2. I also recommend at least 56k power to use this team.

1st round, be sure to use Fire Main's mystery, Gaara's and Killer Bee's on Naruto. If your clone hasn't died with Darui's double hit, it is a good sign, I've passed this level that way.

2nd round, you must have at least 2 clones from Naruto alive to use his full mystery, and target Kakashi, who Fire Main may trigger the chase skill on, and he is supposed to be defeated. Sasuke is also supposed to be defeated, because he took high damage from the 1st round and Naruto's skill finishes him.

3rd round, your Gaara has to be faster than Kimimaro using the mystery and you can focus Cee to make him take more damage. Kimimaro is supposed to be defeated with this skill. Keep using Killer Bee's skill on Naruto if any doubt.

After the 3rd round, I just used Naruto's skill (without the 2 clones boost) to finish Cee. Ay and Darui were defeated by standard attacks.

I hope this helps anyone, and if any doubt, feel free to reply. Thanks!
