Hello,
I am not sure what you mean. Do you want to search by units that only have ninjutsu or taijutsu in their kit? This is not many units. Most of them have some degree of combination.
Please let me know, thanks!

OK, I will add your suggestion to allow these concepts to be filtered in the ninja list.
As for team advice, you will need to go to the strategy section here in the forum or on the official discord for that.
Thanks and have a great day!
