This version of O-Kagachi IS the version that had an aspect stolen from him. This is the reason why the card has the effects that it has (in revenge for it's user being "damaged", he gets to exile something in return.. as if retrieving [that Which was Stolen]).
As for P/T : This is something that has been a problem after the conception of the game. Many creatures remained as 1/1s, but soon after, the game demanded more power and representation and realism was thrown out the window. O-Kagachi being a 6/6 for 6cmc is fine..
I've seen lots of old-blue players having that kind of reaction towards these cards. I still think that is NOT funny
Anyway, is true...from spells going wrong to "redirection", a more comic approach is being used by WotC lately.
(woa...a women playing magic!)
