There are so many scary threats in the FUK Ferrothorn Ubers meta, it's not even funny. Zekrom just dominates, since there isn't a "catch-all" check to it anymore, Palkia is way harder to deal with in the rain and I don't even have talk about Kyogre. I've been told that more and more people are resorting to use Grass Arceus to check the influx of Kyogres, and Latias usage is at an all time high. Dragons in general hit the jackpot, since other than Jirachi, Steels can't really take repeated Draco Meteors. In fact, one of my FUK Ferro teams used 4 Draco Meteoring Dragons XD.
