Dude we literally got a hard counter for them this month. GNW konkuro. Focus their healer and they should go down really quick. Try and protect konkuros puppet at all times. They are actually really easy to beat imo.

GNW konkuro

i use fire main with Ino, in 1st round i can cause chaos to maximum of 3 ninja from his team include the earth, after that you always sleep him and kill the other. Fire Main + tobi = massive damage so you can kill the other ninja so fast. Earth main gonna get sleep + chaos ( by ino chase ) so he can't cast shield.

Yeah, but in survival trial, even if you outlast someone for the entire 10 rounds, you still lose all 4 ninjas nonetheless.

It's 100% possible to beat tanky earth teams using GNW Kankuro and/or Karin. There are many teams out there that work well with those two ninjas.

Yes i literally said you can just put in 2-3 chars you dont need to complete it just to outlast them 10 rounds lol

Sand village is a great 'secondary team' that doesn't require your main to be effective, and if they stall out to 10 rounds you won't miss them.

Gaara, Bakhi, Temari and either Kankuro. GNW Kankuro will likely decimate the earth main on his own, but if you'd rather keep him alive for your main team, use regular Kankuro.

Setup:
Temari, Bakhi, Gaara (facing down earth main)
X - Kankuro - x (or place above main team if would then be facing fire clone).

Sure, won't work 100% of the time, but will work often enough to warrant using them. Get them all to 3 stars, cultivate and awaken and let them rip. Some teams they just decimate unfairly. Others, Gaara's shield and the tendency for the AI to target Bakhi with mysteries means you last the distance and an 10-round the hard team out. At the very least they will likely take down one or two ninja and pave the way for your main team to finish them off

Its not broken you are just using the wrong strategy, if you put crimson under poison and ignite in 3 rounds he dies
