Okay. I just did a quick calculation on MetalKid's DP damage calculator. Max Atk Infernape does 60% on Skarm with Flare Blitz with no Attack boost and easily OHKOs it with 1 SD. Blaziken hits it even harder. If Skarmory can be hit that hard by a physical attack, is it dying? If it's still usable, why wouldn't the previously ignored Regirock be a viable choice?
No, really. Regirock can take both physical and special hits better than Skarmory. It was outclassed by Skarm in the past because it had 2 physical weaknesses and Skarmory had none. But now all weaknesses are physical, so what is there to lose? Also, Regirock can further boost its defense with Curse while also boosting its Attack. Then, when you're about to finally kill it, it can hit you with a Cursed Explosion.
I know there's probably some reason I'm not thinking of, so please either agree with me or show me the reason.
