This.
Black Kyurem literally feels like a fusion of 2 legendary Pokemon. If I told you it has 710 BST (in case you keep up with stats), you would believe me. He screams POWA. And I love it. And, minus SwSh because I don't play it, Kyurem really felt like an Uber even when it dropped to OU. There aren't many things that can survive an Outrage from his boy.
They really did their homework on this one, so you can imagine how disappointed i was when I saw the 3D model.
