Fun fact: Modest Expert Belt Fire Blast in the rain deals a minimum of 73% to standard Ferrothorn. The threat of Superpower and Focus Blast are also huge deterrents for Ferrothorn to even switch in.
Again, unfortunately, he's so goddamn easy to check that I'm undecided on his place in A.
Did you read my last post? I pretty much completely explained how Hydreigon can beat out his counters even with the nerf to Fire Blast, which he doesn't need to rely on since he also carries EQ for Rachi and Dark Pulse for Celebi (Justified isn't a good argument seeing as T-Tar uses Dark moves all the time against teams with Terrakion and Keldeo on them). It all depends on the set, and or what your team needs for him to handle. By the way, I feel that Hydreigon is indeed easy to check, but what about Kyurem-B and Salamence? Mence is incredibly frail and is 4x weak to Ice moves, which are commonly used on Rain teams. Kyurem-B is weak to SR, Mach Punch, Bullet Punch, Close Combat, Outrage, and Stone Edge, all very common moves in OU. I still feel that him being easy to check shouldn't keep him from being A-Rank, since other A Pokemon also can be easily checked. Some of them however, can be countered AND checked, but Hydreigon can really only be checked
