This is another fine example of rulings that just don't exist through the official channels. Personally, I didn't know that TER only affected manual position changes, and it took some digging to determine that you are indeed correct (as you so often are) skey23:

The people I've dueled with don't know this either, as all of us have played TER at some point, and it's always just been assumed that things like
Stumbling /
Book of Moon / etc. simply don't work when TER is on the field. (Or in the case of
Book of Moon, the only card you could legally target was TER).
<rant>
The wording on TER has changed at least once, if not twice, and it could STILL be better. Unbelievable. How on Earth are new players supposed to know these things if they're not published, anyway? Wait until their first tourney and learn the hard way? Not cool, not cool at all.

Thank goodness people like skey23 are out here to make this game worth playing
