It's worse than either the Ogres or Frozen Crusher, easily. Those always got to attack if not removed - this does not. Hell, as I pointed out earlier, even silence won't always enable it to attack if it fails its coin flip, since the "sleep" effect of a just-played minion is only overridden by rush and charge, not silence. And it's not as overstatted as Frozen Crusher, either.
Also, you'll notice than neither the Ogres nor Frozen Crusher ever saw real constructed play, they were just good-ish in arena.
