Secretly, you've harbored your hate-on for Dawn, biding time until the moment is right. Wait no longer. Now, unleash the Wren Boys to track her down and put some serious hurt. There's nothing holding you back. Well, apart from the fact that "The Wren" has to be played and Dawn has to be in play for that to happen, and Dawn's a good guy so you can't have her in your deck if you also have the Wren Boys... Okay, so the card is admittedly narrow in its application, but if your opponent is playing a Wren deck, there are few cards better to shut it down.
