I clear full survival and all 5 breakthrough on one team.
Haven't lost the team in months and only lose 1 character every month or so on 3rd or later breakthrough.

sage naruto, GNW kankuro, wind main, jigokudo, in that order. Placement varies depending on opponent, try to get 1st turn chain off sage naruto or GNW kankuro's normal attack (which guarantee low float, which leads to fun stuff), ensure kankuro puppet is NOT in front.

Before this I used empress, sometimes replacing karin with sakura. Empress is good for getting through without a scratch if you can't full sweep first 9 yet. After which you have extra character all at full health to burn at the "boss" nodes. And thanks to predictable AI, you c*ually acupuncture his 2nd turn jutsu.

I think survival used to be harder, I used to get people who are stronger than me, which was the last time I had to burn an off team to pass(entire team designed to kill off one key combo/init char) cause the ones stronger than me are all ptw and even * AI dont make it ez. I haven't gotten those in 2 or 3 months. Now the strongest are players who are in breakthrough and usually 1-5k below me. I usually have 5-8k power on the guys at node 12.

In any case, key to survival is sustain and damage mitigation (cc/hinata/shield/clone block, whatever). Most fire or lightning PvP team won't work in survival because they tend to win at cost of suffering damage. (which in turn, was the easiest to burn an off team to beat back when survival was hard. After the first two week or so, I only failed to full clear survival + breakthrough a handful of times, less than 5 I think, all of which is due to a stronger Earth at 12th node. Even burning off team isn't enough to BEAT him, ending up timing out my main team afterward, thus while cleared survival, unable to continue to breakthrough, GNW kankuro was my salvation, as soon as I got him, full clear everytime.)
