[quote name='sblymnlcrymnl']Summoning (well, not technically) a house is nifty, but how useful is that in battle, really? :lol:[/QUOTE]
I dont think it got summoned, he created a house. Imagine you kept gettin put in houses, pretty annoying. Kakashi has been in 4 major fights, Zab, Itac, Rock Nins, Deidra, he has not won all of them but he hasnt lost either, but the end of each fight we see him knocked out and in need of medical treatment. I think hes great but his new technique he used 3 times and hes been out for over a week. Imagine he missed with it he would have been crushed. Also he nor anyone else sensed that He/She was still alive. He has been fooled twice by that now.
