I was playing against a n00b deck that had Mew SW, and the kid used it to recover from like no hand to nine cards! It hurt me a lot since I try to keep their hand low, and that wasn't happening! I really don't like it used as a recovery tool. I personally would go with Copycat, Steven's, or Birch. It is not worth giving the opponent an opportunity to an easy prize, as well as not physically damaging them.
