Hey,
Kiti here from S11 Choji, with a few tid bits for Azure Fang players that are new. I've spent only 5 dollars on this game, and that was to get Gaara. The rest is just hard work. Now, this is my first guide, and it will probably be pretty bad! Im okay with that :) But since people struggle with some combos, i'll list a few that have worked well for me. Take note, im no expert, but I seem to do okay.
My current team is:
Main with Healing as mystery, healing as attack, passives are chakra blade, healing tips, and poison tai. This is a level 55+ Combo. You'll want to use the following ninja:
2 or 3 star Hinata as a tank on first rank. Kiba great ninja war, sasuke 3 star, and Main. Summon: Gamachu - in order for this to work, you must have Gamachu, he is great for this combo setup.
Previous teams:
Level 35-40ish team was Gaara, Kakashi, Karin and Main.
Level 45ish team was Karin, Neji,(3 star) Kakashi and Main.
Level 50ish team was Karin, Hinata, Kakashi main.
Note for above to keep in mind is, you have to change your setup. I know with the level 50 team, you want Water clone, water whip, neurotoxin and shark bomb. Either tai attack or nin heal for regular round attack. More or less the same with 45 team, but you wont have the clone, or whatever it is. The 45-55 team is good, not too bad I dont think. You're biggest issue will be Lightning and rock folk. Hope this helps, a little! I might edit it later on, if people think its half decent. I typed this up in like 10 minutes :p
