first we dont really know if yagura had complete control second this isnt the 8 or 9 tails so maybe that power was weakened. third Madaras genjutsu isnt basic genjutsu he uses eternal mangekyo sharingan, which is way more powerful D!ABLO-32: 1st - read hear 2nd - Killer B never said that having full control of ONLY the Hachibi and Kyuubi will prevent one from falling under a Genjutsu, he meant all Tailed Beasts. 3rd - MS Genjutsu can be broken, even Sasuke proved that... Therefore, I don't see a full controlling Host having a problem...
