I've been saying more teams carrying both Landorus and Thundurus (incarnate forms). I'm doing it myself, too. It's great, because together they add a lot of speed to your team, and Thundurus covers the speedy/priority pokemon who may give problems to Landorus (Azumarill, Keldeo, anything vulnerable to Thunder Wave), while Landorus breaks walls that Thundurus may have problems breaking.
On the subject of Landorus, the Therian forme with a Choice Scarf is now becoming a trend. It used to be that every Lando-T was the classic pivot type, with Stealth Rock, U-Turn, Knock Off and/or one or two attacking moves. I think that became so predictable that people started moving to the scarf variant, and now it's not safe anymore to stay in and use special attacks, because once Lando outspeeds you, that 145 attack hurts.
