Gotta know if you have any other non f2p ninjas(specifically event or kage treasure) to truly help. and the people your usually facing. lms with sword? or do you fight alot of fire still

combo amount isnt that important. What is important is utilizing buffs + a combo that uses darui to paralysis

So your goal should be 3 total sword ninjas with Lightning Main + 3 total lightning or water, 4 if you can do it.

Kimimaro is a good tank as well, since he uses 60chakra hes a solid member that will let you use darui turn 2, kimimaro turn 3. Utilize LM acupuncture or armor to go round 1.

So My personal preference would be
Darui/Lm with anbu ops + root of the warrior --((ALways this))
----
Kimimaro + Kisame + a repulse to knockdown chase + Knockdown to high float summon
Kimimaro + Sai
Hinata + Suigetsu

You really need to use kimmimaro + any other water/lightning who can help darui use his paralysis combo
OR
Hinata + a sword ninja.

- also try and pick characters who use Tai primarily. if they use all NIN itll mess up anbu ops.

- the only long combo that matters is from daruis aoe. but even then +buffs + a tank + leech effect(this is why kimmimaro is so good)

if you paralysis combo 1. make sure you focus wind main on turn 2, if you use hinata she can acu her. and stop her cleansing mystery
