finally
how can you swallow so much sleep?
you usually won't see ttar except in tour play. the amount of weaknesses it compounds is usually too much for sustained successful ladder play. although deemed inferior, dd wp tyranitar is probably the most common one you will see used because of tyranitar's ability to take a hit, set up, resist brave bird and go ham.But what about stuff that are losing their spot on the metagame? I almost never see TTar and Cresselia anymore, and they're both awesome mons. Same goes for Bisharp and Terrakion. I've also seen weather going down in usage, the last I saw a Rain team was in Mediocre Mons a few weeks ago. Support mons are going down in usage too, Top and Amoong are rare in the ladder, I almost never see them anymore too.
Qazoo306 a good way to deal with special attackers is assault vest. the benefit of this item is that you do not need to switch (like intimidate) to activate it and you do not need to use a move to lower the stat (will o wisp). im sure you know the downside of av though (no protect)
Nollan pony is pretty good and i think viabilitys are wrong ;]. i think mega venusaur is not entirely as a result of needing a check to keldeo, but more a result of newer players experimenting with non-kanga megas. there is a stage of teambuilding where you want to use more than just the kangaroo, and i think multiple PS doubles users have reached that point simultaneously.
