How can Obito combine 4 different nature transformations?


How can Obito combine 4 different nature transformations, if he barely managed
to control the Juubi inside him?  
Using advanced techniques and nature transformations needs some focus on
chakra manipulation, so how is he able to do this?

Obito is the Jinchuuriki of the 10 tails. Having the blood of the Uchiha +
having the Rinnegan and the Mangekyo Sharingan + being trained by Madara
himself, Obito would have surpassed any living ninja in technique and chakra
depth, as well as natural talent. It was even said at one time that he was the
same as the "Sage of the 6 paths".
