onoki and muu combined with a few jintons can clear out the susano clones.tsunade can replenish chakra.
hiruzen figures out which one absorbed the jinton and RDS him. remember muus a sensor, he can discover which ones real. i dont think death god will actually tear out a clone since a clone has no soul. the hand of death god would just pass right through. and since its invisible till its too late, hiruzen defeats him.
