NU is diverse, so as long as you carry something on your team that can deal with Altaria, Slowking or Lanturn respectively then you should be fine. :)
Scarf Magmortar and Sawk give them problems, admittedly, but they are still quite the challenge.
GTM, which NU are you playing?
Those are all minor threats at best; what you should be afraid of is mesprit, gardevoir, magmortar, gorebyss, hail in general, and sawk, among others.
Why the fuck would someone use defog?,it removes hazards from your opponent , not yourself unless someone is crazy enough to use Natu(almost no one do this).With the lack of Spinners in this tier, using Defog could become somewhat usable. The pokes that do learn it are almost all Flying, so they may take SR damge, but people are using Cryogonal (which is obviously weak to it), and the flying types have Roost for recovery.

I've seen one TR team and I recall having lost to hax; I don't think it's terrible, but I've yet to see its full extent.
Also hail scares the everloving fuck out of me. Literally every blizzspammer, not to mention walrein, is in NU. Scarf Magmortar and Sawk give them problems, admittedly, but they are still quite the challenge.
with Magneton moving up to RU, Klinklang and Swellow will definately have an easier time swepping. Klinklang in particular will probably dominate NU during the next month or so.
When the RU analysis is finished.NU needs its own subforum.
I haven't played too many battles, but so far I've found Regirock to be a huge asset. It completely stops Swellow, can take all kinds of physical beatings from things like Altaria, and provides amazing support with Stealth Rock and Thunder Wave. It hits quite hard with Stone Edge and Earthquake as well. Even Magmortar has problems with Regirock with that nice resistance to Fire-type moves.
Also GtM that Magmortar set is really good even outside of sun, especially if you have something to take on Altaria effectively.
I like restalk curse rock slide better as a sweeper.
TR could definitely work. I doubt that any team could stop the combined efforts of marowak and rampardos if they can keep tr up. Stuff like OTR duosion and slowking and octillery could handle any physical walls.
Oglemi, the list in the OP has Alakazam, Venomoth and Yanmega listed as RU.
