Kabuto is the best healer in my opinion, and his fragments are available in Survival Trial. I don't know how he combos with Temari/Kankuro though.

Kankuro is a great choice in later levels because so many people choose Hinata, who blocks pretty much all taijutsu for a round but can't block Kankuro. Plus poison is a fairly useful debuff since it stacks. If Shizune (I don't have her) combos with Kankuro, that'd be really good, I think - double poison + heal.

Once you unlock Shadow Clone you should probably avoid conflicting with Naruto 3*, who spams clones like no tomorrow but they're really one-hit wonders, whereas your clones are pretty sturdy.

Hinata is incredible against taijutsu teams, especially across from Lee (she just blocks him).

So those are my suggestions. Maybe try them out against the Kakashi clone and see what works.

Hope this helps~!

Try moving Kiba back one so he doesn't die fast, and if you have GNW Kiba use him instead.

Unfortunately not yet, but it's self-explanatory for the most part; use the dropdowns for main. Worst case look up "fire", "wind", etc. on Google Translate for the ccharacters.

But I don't have him for combos, it's his clones + heal. And he does combo with fire main/Kakashi/GNW Kiba, so he works for me. Depends on your team.

I understand not wanting to pay. I'm just not allowed to, even for four bucks for Gaara; and there's a sort of pride in being a successful F2P. I support the game by telling people about it. So don't feel bad if you just don't want to.
