"Claydol moved from RU to NU"
Given the changes, here's some things that I will predict to fall or rise.
Cresselia - Pre-Suspect, Cresselia was the bulkiest thing to handle Dragalge, M-Sceptile, and M-Pidgey. Unfortunately for her, all three of these suspects are gone. With Gligar gone, this also hurts Cress, as more people will shift towards Golbat which makes running SubCM, one of it's flagship sets, even more difficult to run. The new tier changes will shift the game style back to what it was during the "Blind Burd" era. (LO Moltres, Specs Loud, LO Hitmonlee, ect.) It could possibly be even worse thanks to new popularity in Pangoro and Houndoom. I expect it to drop down to B tbh. :T
Bronzong is also on this same boat as well.
Golbat - Golbat got a MAJOR boon in the form of one departure. Despite losing some appeal of walling stuff like Dragalge and Mega-Sceptile, it has gained a huge amount of appeal with the loss of Gligar. Now he arguably stands unopposed as
the best defogger in the tier. Skuntank or Swanna may try to catch on but, Golbat boasts an amazing defensive typing, along with some pretty hefty bulk w/ Eviolite. Walling nearly every popular steel-type (Minus Magneton) and goro is a pretty big thing. A-.
Moltres - Moltres will centralize the new RU tier. I'm calling it right now. Some of the enemies have changed but, this tier is almost identical to when he was stomping around as Blind Burd. His teammates will change but, his sheer power has stayed consistent throughout the changes. Very few checks or counters have been added to the tier to stop him from being a monster to both Offensive and Defensive teams. Simply put, this tier will fit like a glove to turkey nuke. S+ if possible.
Amoonguss - Thanks to the suspect tests, Amoonguss can rear it's shroom head in as a very annoying wall to face. The suspect tests alone give birth to the revival of more regen-cores. M-Glalie and M-Snow may prove to be a bit of a rough transition but, I think Amoonguss will be able to be in a respectable place in RU. Possibly moving up to B+ or A-.
I'm a bit excited to see how this tier is gonna turn out. With Gligar gone, it opens up some walls for us to look at for defoggers. Especially with some of the OP stuff leaving, I predict this will be a pretty fun tier. c:
