Ok narutobase i feel like i need to address this.... madara is smart as hell people think really hard about his actions up to this point... he knows hashi and he knows his tricks if you read back madara was the only one able to see thru hashis woodclones in the past as his enemy... think about this scene

ok madara is obviously able to read clones easily due to his sharingan this is the single most important page of the manga this is how madara acquired hashiramas DNA and made his plan he did see thru that wood clone guys.. after hashi left that woodbushin he left was the DNA madara needed to start his plan and get his rinnegan... this is honestly the best theory i thought of hints from todays manga made me think about this if madara saw thru the clone in a single moment why couldnt he tell back at the final valley? the answer is he could and he did even if you say he had no chakara how else do we explain him cheating death..
