That team sounds really cool! Mei + sage Naruto is one heck of a 1-2 punch, but (Im really sorry about that but...) you have one major problem. Poor Scarlet blaze has one major flaw, everyone is tired of hearing it, but it has to be said, Root of Warrior passive completely destoys him. Most of the damage and skills that the fire main relies on is mostly ninjutsu based, his other strenght is the use of multiple debuffs, all of these are completely nullified for 2 turns by the lightning mains, plenty of time to gain a sizable advantage. I highly suggest you stay clear of Scarlet blaze for now, someday he will come back once they release the jinchuriki Han, but for now I suggest you use Azure Fang with that same team. You might also want to try Sakura sailor uniform as a switch to Hanzo, they are both interchangeable depending on the meta you are facing.

You are going to get shrekt vs lightings mains and also no one will buff your sage naruto cool ninjas but they dont work together xd :D .

This obsession with buffing all ninjas in your line ups is preventing people from thinking outside the box. Sage naruto is an excellent ninja on his own, he has his own strenghts and can be used in many line ups that dont exclusively buff him. For example, he is one of the best delivery system for Azure fang's poison tai passive. You dont need to buff all your ninjas if you have a clear plan to victory.

Well do whatever you want im just saying what i think sage naruto deosnt get any kind of boost neither does mei expect her barrier ( if she can keep barrier up ) , idk about hanzo and firemain dont think they get an insane boost aswell xd.

Mei boosts fire, as well as fire main. Mei also boosts her self. As for Naruto he is a Tank so i don't think its a big deal not having him buffed. If you know a good replacment for him tell me tho.

Hey i read the comments and gave it some tought. How does Mei, Mifune, Hanzo Lightning mei sounds :D With dog of hell Max combo it can get is 7 on every single persons mystery or auto not including hanzo for obviouse reason. And what talents would be the best? If you think this is a fail idea then i give up my theory crafting for now :D What are some good hanzo line ups?
