You didn't understand the point and somehow it's my fault, because I have a different opinion to yours.
In that case, let me answer to each point, so I make myself clear.
As the first is concerned, the cores are mainly teams of two pokemon that are used, and have certain goal in the team, as Skarm&Blis or Ferro&Jelly and so on. Usually you come across defensive cores, as the offensive side is later created. As I stated before, you don't just take 6 individually strong pokemon and call it a team.
About the second, dragons have come to their checks this generation. You used to see teams with 3 or more dragons. Now 2 is the max you'll see, and that is rare. The reason they were overused were their generally high stats. That is why you'll still see their usage. What is now in control is the spam of outrage, with or without fairies.
They are no more the solution to everything, not only because of the intro of fairies, but also the great range of different pokemon, along with megas introduced in this generation.
The concept of having certain moves in order to lure your potential checks in is quite old and most often seen in HO teams. While Wow is less common on a Talonflame, Magma Storm is often seen to replace Lava plume in Heatran. Other examples include Superpower Scizor, Dazzling Gleam Gengar and IceFang Gliscor. An agility Metagross carrying Hammer arm is also a lure set, targeted at other steel types, and especially the now rampant Magnezone with Hp-fire.
Greninja could also be carrying something you'd call a lure set. Given how frail it is, as already stated, it can serve as an one-use surprize which might be helpful or not, as it depends on the EV spread in the end. The reason Gren is suspected now is his two new moves, Gunk Shot and Low Kick, both physical. This mainly means viability as a physical attacker or having 1 physical move and 3 special, to serve as the problem solver who provides coverage. (already adressed in the previous post).
You posted info about cores, the usage of dragons and the possibility of greninja running a lure set, yet failed to explain where you disagree with what I posted.
You merely assumed that the others don't know about the metagame. Let me answer to that.
A) I have playing in OU, mainly in Smogon, since generation 5 came out. At some point I became good enough to win several tournaments. It used to be mainly individuals hosting tournaments on challonge, yet since gen6 they host them in the main showdown server. I've been in those and won some, some with few and some with more people.
My experience is mainly with smogon rules.
C) I am currently participating in this suspect test on showdown. I reached the 2700+ COIL mark and am eligible for voting. Previously I was eligible to vote for/against the banning of M-Lucario, Genesect and Deoxys-S, about a year ago.
D) I'll have to agree with you on this one. Nobody likes to play a broken tier.
