[@BladeSS4] 'more chakra' is not a trait of the Uchiha clan. I'm not sure where you heard that but it's not true. And if the original Tenshi uses even one jutsu/uses a bit of chakra while none of the clones has died, he'd pass out. Although we don't really see it except at the start of Naruto, using up a lot of chakra can take you down. 

When Sasuke trains with Kakashi to learn chidori, he can perform two. He asks Kakashi what happens if he makes a third, and Kakashi says he'll die. That's how serious it is. Know your boundaries.
