Upon realizing he is revived by Edo Tensei, Uchiha Madara even took advantage of reanimation/immortal property of Edo Tensei by using an ultra strong jutsu that even killed him and Muu but then reanimated later. They(Madara and Muu) should have been also weakened when they got hit by Madara's jutsu(Meteor-like giant rocks from the sky). When chakra is depleted like Kakashi did, the user/caster will die. But with the property of Edo Tensei, I wonder if what will happen if Uchiha Madara spams high level jutsu which uses loads of chakra. What do you think guys?
