Play smart. Wait until they use their mysteries. Its a hassle but not impossible. Its hard to recommend a team without knowing what ninjas you have and what your main is. In most cases if youre lightning you'd probably have to switch simply because you wouldn't be able to outdamage that in arena. you probably could kill han with blitz but then sailor and mei will eat you alive. Most other mains stand a chance. Debuff clears like gaikido will help. Run a healer.. Also burst comps go a long way as well.

Against the team you're having issues with currently in arena.... wind main with sage Naruto, Gaikido, Regular garra makes pretty quick work of them. Play around with it. you can swap out Gaikdo for Jigokudo or even Bee.. Although regular garra doesn't have cc, his damage and barrier override make up for it. Plus he shields as well. I personally always focus mei first or water main. that situation. A fun team I used to play around with was Kurotsuchi, Garra (normal) or kazekage, GNW kank and wind main. Being lower initiative youll want someone who can kill barriers. But you honestly have a good amount of chars to counter teams like those.

Valid statement. Always keep that in mind. I pay and there are comps that wipe the floor with me. Take your wins where you can get them.
