i think what he means is the moment you attach it, as technically tengu is on the field, and when it gets attached it becomes "not on the field", so technically tengu should activate at that point
but i heard its something like returning it to the deck and that its effect doesnt activate when you do that so yeah
correct me if im wrong though, im not too sure on this
