If you're using Lightning main with Anbu Tactics, doees Choji get the Taijutsu and Defense increase every time he heals himself with Tai damage from that? If so..that would be very powerful, but otherwise, Lightning main doesn't have that much synergy with Choji. But yeah, let me know and maybe I can make you a team with Choji and Guy.

Here's what I think is the best team.

Yup, it's Ino-Shika-Cho. These ninjas are made to work well together because of that connection, and so they are the best combo you can put with Choji out of your current ninjas. GNW Ino and Chunin Shikamaru might be a bit frail because they are only 2 stars (I would highly recommend getting Chuunin Shika to 4 stars, he is a really great support character with his breakthroughs) but they will buff Choji a LOT. Everyone on this team is a secret jutsu user ninja, and Ino, Shikamaru, and Fire main all buff secret jutsu users. So you should be hitting pretty hard.

Ino will also heal Choji if he gets low on life and trigger his scaling when she does. Also, having Shikamaru on the team makes Ino's mystery hit two targets instead of just one. I haven't tested this myself but I'm pretty sure Ino should also chase off of Fire main's standard attack and cause chaos to units he put to sleep. That, along with Shika's chase that can cause immobile, gives this team a pretty strong control element as well.

Edit: Forgot to mention, if you use this team you can probably use Choji's Y chase instead of his +1 chase, because you should be able to reset your own mystery cooldown without the +1 doing it for you due to the Red Lotus Secret passive on Fire main. However if you try this and you don't often get the reset, you can switch back to the +1 chase on Choji.

Also, you can put Swimsuit Ino instead of GNW Ino if you want a non-2 star ninja. But she doesn't give the secret jutsu buff and she doesn't have that thing with Shikamaru where her mystery will hit an extra target.

Ah cool team. I think I should try and Four Star Shikamaru so that I can skillbreak him. Thanks!

No problem. Yeah Chuunin Shika is really nice with BT, and now that he has skill trials getting all his skills done should be a lot faster lol. Go for his Hidden Jutsu Strength passive BT and his Y mystery BT first in my opinion.

You can put him on a lot of teams, and a lot of powerful ninja (Uchihas) in the game are tagged as secret jutsu users so he can support them too.

Which 3rd ninja you could recommend for Choji GNW and Ino Summer(not including rare ninjas)? I thought first add this ninjas to Fire main with 4 3 4 3 1 talent + Kurenai(because knockdown>repulse chase), but then i thought that maybe reroll main to water healer and add someone else as last ninja, but i don't know which one could be good in that lineup.
