Look, I agree this card is not meta breaking, but it is very good. There is absolutely no need to build a deck around her.
Ysera, Wyrmguard, Nightscale Matriarch, Witchwood Grizzly, Stonehill Defender and Tortollan Shellraiser are all good to amazing cards on their own, but they become really crazy with the Lady! That is already so much value you can also add a bunch of spells and minions that do not benefit from her. To make sure the deck can succeed without her. Like more dragons, a Lyra the Sunshard package, or Spiteful Summoners.
Now if you just put some unplayable garbage like Shieldbearer or Street Trickster in there and expect the Lady to make it great... that would be some stupid deckbuilding.
