Just gonna go over this article pretty quickly, and present my.own thoughts.
Dragons, plunder, Lurk, Sivir, and Sion are solid midrange decks and for that reason they are good right now, are they exceptional, hard to say but solid 9/10 decks for sure.
Lee Sin Zoe...no just no this deck has never been worse right now. Enjoy getting minimorphed, getting your eye of the dragons removed etc.
I would add quite a few more to the list, I belive landmark aggro with Renekton post buff and Ziggs can do some scary stuff, kind of a low ramp midrange list honestly.
Top end wise, turbo ramp into like a auto leveled Asol is scary as hell. Probably a lot worse with counters, but as something you run into once in a blue moon you'll get run over.
The buff to nightfall is actually relavent where playing multiple Champs still gives you his play effect, turns out thats huge. You can run better decks but you can climb with this.
A high rolled Ekko can be absolutely disgusting, I've seen some r and g nightmares where they pull crystal and duplicate it and play ekko leveled on curve into a automatic time wind, like really unbeatable situations.
Swain, Viktor, these niche Champs are also seeing some really strong winrates again due to their midrange identities, Lux can do work, and yes even in very small instances Braum.
So yeah play midrange or aggro-midrange and win games...that's the real lesson from the post patch meta.
