Fraud
Yo this mon stinks. Tyranitar is top 1 splashables right now, competition from Regular slowbro which provides a better check to the former Luke, aswell as better vs Gallade, and checking Armarouge if you feel like taking 85% from an armor cannon. That aside, Slowbro is far superior and drastically outclasses this thing. Losing scald is terrible as it lets Ttar seemlessly check the cm sets that made it dumb last time. Yes, it has coverage for ttar, but slowbro doesnt need to waste a slot for that when it has it to begin with. Overall, not worth the trouble.
God
Yes, I'm including booster energy among the brokens ranking and here's why. First though, I will reiterate that while precedent doesn't exist in official tiers, Godly gift, Camomons and multiple other OMs have banned booster energy, so this take isn't an unreasonable take. For starters, this item specifically absolutely pushes Iron Leaves over the edge, being able to get a free scarf on your sweeper which has clicks that consistent is a fast track to a clean sweep, with options like priority from bisharp and MMQ stifled by Tera. Iron leaves isn't the only abuser though, Slither Wing's Acrobatics set is very goofy and lends itself to cleaning games up fairly easily, and most tera options to stop it are either incredibly telegraphed, like tera ghost ttar and Bisharp, or just don't kill it after a Bulk Up, in the case of Emergency Mimikyus (because play rough sucks use drain punch). And frankly, most tera mons don't pick types that resist flying, so acrobatics is generally, very free.
>Says Iron leaves is busted
>Insists on using regular slowbro over glowbro
I think regular slowbro is better because of the future sight, better stats and water resist, but does regular slowbro resist fairy? Glowbro still has its uses and whichever one I use depends on what the rest of the team looks like. Calm mind is bad and body press is a must on glowbro in order to lure tyranitar but body press isn't just for the tar, it also dark and steels and allows you to run a different move than flamethrower as your second attack. Also, shell side arm is a lowkey good option. Without calm mind you would end up being bait for calm mind fairies, but with shell side arm you still do 50% to max physdef florges with your poison move, it's also relevant if you are the one person in the world who had their sludge bomb blocked by chesnaught's bulletproof.

. These two don't really need any explanation. Gyarados just beats everything and will never trade for less than one and a bit pokemon and Leaves is just pure bullshit.
, 
. I would not mind Mew going at all but I get the feeling that it might be less of a problem if two if the biggest HO threats were banned. If waiting and seeing is an option I would endorse that. I have barely seen any armarouges so I just don't feel qualified to comment. However I have a 75% win rate against it and the only time I lost to it was because of a Draco meteor miss, so maybe it's garbage.
, 
. These two I feel are positive forces in the tier. Slither Wing is strong, but ultimately it's fair and honest. It has a few viable sets it can run and most of them help keep broken stuff in check like banded first impressions for revenge killing speed boosting sweepers or tanky pivot sets being solid glue spreads status and provides pivot support. Jugulis is kind of overwhelming and it can just muscle past the pokemon that would claim to check it, but I feel like it still has good vibes. Booster energy is unbeatable in the late game and I agree it's a bit unhealthy, but I find boots and choice sets help more than booster energy hurts. Like slither wing I find it being a kind of glue mon due to its really useful typing, having taunt+knock+U-turn and strong stats. Jugulis and Noivern have just been really welcome upgrades over our old fast fliers of kilowattrel and Tornadus because of their better stats.
Toxtricity and free 
Lycanroc. Toxtricity is still way too strong and can just win the game on the spot if you guess its set wrong and Lycanroc has never done anything wrong in its life. You people really saw 50 speed boosting sweepers, half of them being flying or fire types, drop from UU and then decided to not unban the pokemon with strong rock type priority?
. I still wanna tune the team a bit, but I wanted to share a specific mon that has been the biggest surprise from the shift:
