Everyone knows that Ninetales' worst match-up is Metagross. Not because of Metagross GX, since it is walled by Baby Ninetales, but because Metang is a one shot on Baby Ninetales due to weakness. I was at my locals and saw a Greninja player using Weakness Policy. Obviously they use it because of Tapu Bulu GX. Why not use it in Ninetales and turn that OHKO to a 2HKO?
