@Thekillman: This technique was specifically made to counter Obito's MS ability. She had been monitoring him for years. It wasn't stated whether or not she begun the preparation for this technique during that time, but she even confirmed herself that she had to amass 600 billion paper bombs to kill Obito. That's not too hard to believe. She is an Akatsuki member, after all.
