There are times when I have used this strategically. One such time was when I was playing against a crusader rainbow deck and I didn't want my pulvy copied so I destroyed it, waited for him to endow his crusader with his own owl's eye, then played the pulvy in my hand.
I would ask that people refrain from saying "There is no strategic use" for something just because they haven't thought of how it could be useful. Perhaps a "I can't think of how this could be beneficial" would be better. Yes, I know, I'm arguing semantics and whatnot, but I would hate to see an action taken before all possible angles have been explored.
