not sure Madara passive 1 works how you think it does, most likely its should be stated as such,

so long as madara is alive konoha units will have their nin and attack buffed by 25%, In addition if a konoha unit casts a mystery madara will generate 40 extra chakra and recover 20% of his life.

A different type of op then whoever casts get the healing, since this means madara can go from near dead full heath if mysteries are spammed and he's not on fire, and works much better in down to 1 unit both case then say so6p naruto since leech requires easy to damage targets to work well, while madara can heal much more at that point ( as quick maths a 50k hp madara can heal 10k every other round, for naruto to match that he needs to deal 20k damage, which is not happening at that point).
