Landorus-T seems like a over-preparing for Terrakion,which hasn't been picked yet lol,as Landorus-T itself matches up bad against Team 1 when they have a Rotom-W and sheer force Landorus-I.
I understand that Terrakion is a big threat(That's why I nominated it lol),we should by no means over prepare as Team 1 can easily pick something else and put us in a bad situation.We have Celebi who can take Close Combats,Keldeo can tank a Stone Edge or two and revenge kill.That's good enough for now.As it means we are not weak to it.But if team 1 do pick Terrakion,only then we should think of a dedicated counter/check or tweaking our nominations.
Also,our current options are not friendly to terrakion at all.They can threaten it in someway.Speaking of the nominations,I'm not sure if ScarfLoom would be a good pick.Sure,spore is nice and it can check some of Team 1's pokemons.But we already cover Team 1 pretty well.While ScarfLoom's super fast spore is menacing,but other than that,it doesn't put too much pressure.We already have a scarfer and revenge killer in ScarfKeldeo and we should avoid multiple scarfers as they can easily be turned into set up bate.BW2 is abundant in powerful sweepers.Not to mention after you use spore,they opponent gets a free turn,something that could easily change the course of the match.After all,it is Team 1 who has the last pick.
