I mean I can't entirely give you the BEST lightning main team...but this team will be costly

Ninjas:

Sasuke (Rinne Sharingan)

Naruto (Kurama Mode)

Jinpachi Munashi (Edo Tensei)

Lightning Main

Summon:

Monkey King

Summon Mystery:

Giant Katsuyu

Treasured Tool:

Healing

Talents:

Chidori Blade Shadow

Beam Of Light

Lai Giri Decapitation

Anbu Special Assault Tactics

Clone Combination Tactics

Well any team with the new $3000 Madara is a real killer, hence the reason why I didn't put in that Madara in that team, as this Madara can basically destroy any team with his immunity.
