@combatIQmatters: We have no idea whether Kakuzu or Madara would have any knowledge of shadow clones or not. It's just a fact. Tobirama may have come to Hashirama's aid when Kakuzu attempted to assassinate his brother... but we don't know. Because it was never addressed in the canon. All we can do is take canon evidence and apply it to these x vs y scenarios.

Both Madara and Kakuzu could have been very aware of shadow clones because Tobirama was the inventor of them and he was very active during both of their lives. However, Kishimoto never confirmed whether either of them knew about it, so we can't make a decision one way or the other.

All I am saying is that Kakuzu is evidence that being experienced does not mean you are guaranteed to win.
