I agree with Nick on this one. If the only effect of TO would be to transform into something it would be called Transformation or Duplicate or Copycat or whatever.

Now the user takes over a certain thing and controls it to his/her liking. Besides, TO has always been one of those vaguely established magics, so it isn't that strange for "new abilities" to be revealed.
