If it's the only thing that can stop them, guaranteed, it'll start existing. Modest 252 Specs Mewtwo counters any Kyurem that isn't scarfed, and that's assuming they're as bulky as possible. Chances are they won't be and you can run a scarf and still get the OHKO. (Edit: Nope, not happening lol)
Metagross seems promising, it can OHKO with Meteor Mash and is rarely 2HKOed by a banded Black outrage.
Poppy edit: I deleted one of your earlier posts, but i'll leave this one here as an example; it is not okay to propagate blatant untruths back only with stupidity and a cocky, presumptuous attitude.
Take this as a warning, next time I'll infract.
