life is generally the best option for 'support' ninjas.

i would say +life -atk

just put him in the back of other ninja, his passive is to dodge chase , not standard attack, of course he die if he get put in the front.

My Madara5k is mooded with +life/-nin .. I don't know if this is the best or correct one but this is what i'm using .. He's at my pos2 wearing semi-upgraded equips/runes, he can survive couple of rounds but it is really expected for him to die specially with poison/ignite in play ..

hummm i used ninjutsu mood on mine, but it makes sense, using life mood, his standard kinda meh, but his chase is amazing, due to ignoring bit def / resistance from the opponent that's where he shines.

I tried stacking combo runes on him. Love how he could immobile anyone randomly. Rng sometimes could be so good that he chase the ninjas that i want them dead xD

i put +hp - atk on mine.

He can get blitz with Light main + Madara team, even removed barrier and temporary buffs.

Or there are some undodgeable chases like Kurama can get him also, since he doens't dodge mystery.
