The wording is actually fairly interesting and unique. In multiplayer games, it's asymmetrical enough to give you an advantage, but not in a way that paints a huge target on his head.
Even if it's the only creature you control, it paints a big target on everyone's head but yours. Nobody wants to swing into him and kill the goose that's laying the golden eggs, but it certainly incites your opponents to attack each other and leave you the hell alone.
