Gligar is not Gliscor. It is nowhere near as good as Gliscor was and can't even come close to competing with it. However, Gliscor was arguably the best Pokemon in UU, certainly in the top 3. The idea of "replacing Gliscor" is nowhere close to accurate due to thehuge gap in viability: Gliscor was S rank and Gligar is being nominated up to C-, the lowest rank of viable Pokemon. The rank for Pokemon that have a small niche in this metagame. Gligar's ablity to switch into several Fighting-types like Cobalion, Terrakion, and Infernape as well as several other Pokemon like Mega Manectric if not running HP Ice, which is far less common, Mega Aggron as stated above, and several other Rock- and Steel-types makes it a niche choice on some teams, and that should be reflected here.

Rotom-H is a really good pick right now. Not only can it act as a really good offensive pivot for a variety of playstyles and teams, it's also a very slid Flying resist option. For the last few months, Flying-types like Moltres, Togekiss, and Crobat have been rising in viability, and Rotom-H's ability to act as an offensive check to them is appreciated in a metagame that's full of these Pokemon. It can also threaten bulky Steel-types like Klefki, Scizor, Mega Aggron, and even Empoleon to an extent while also walling Mamoswine's STAB moves, only losing to if it's running the rare Knock Off or Stone Edge. It has a lot of great utility options like Pain Split, Defog, and Will-O-Wisp too, which allows it to fit on several teams. Its ability to fare well against much of the metagame means it's deserving of a rise.

While Azelf may be the most reliable suicide lead in the tier, its usefulness in this role isn't as prominent anymore, so it should drop a rank to reflect this. Some hyper offense teams are shifting to be more focused on a Mamoswine / Klefki / Sharpedo core as opposed to ensuring hazards remain up with lead Azelf, and the teams that do keep this can struggle to break through a lot of top-tier threats. Azelf also hates the rise of Choice Scarf Krookodile and Hydreigon. Mamoswine's reintroduction brough offensive an extremely strong Stealth Rock user that isn't forced to faint turn 2 or 3, and it also brough another priority move, which can be problematic to some of the staples of these teams. Aside from its role as a lead, Azelf is far too frail to reliably become an offensive threat, and while offensive Nasty Plot sets are an option, they require a lot of team support and are far easier to shut down or revenge kill compared to other Psychic-type setup sweetpers in Calm Mind Latias and Nasty Plot Celebi. Azelf's role is not as commonly seen, so t should drop.

Lucario is a really good option for an offensive Fighting-type, especially on hyper offense or offense teams. It can presure a lot of the tier with either one of its boosting sets; Swords Dance allows it to become an extremely strong breaker with Meteor Mash and Close Combat as well as being able to use Extreme Speed to weaken almost anything that's not Rock-, Steel- or Ghost-type. Nasty Plot, arguably the better set of the two, has a really good matchup against stall and bulky builds; Blissey fails to reliably wall it after a boost or two, and Quagsire's weaker Special Defense means that can be bypassed with a Z-Move too. Both sets are powerful enough to find setup opportunities against a lot of more passive Pokemon and Pokemon that can't break it due to its typing, and its typing can also create setup opportunities from the switches it forces. This amazing breaking ability with the lack of Gliscor and Venusaur to wall it made it, along with several other Fighting-types, a lot more prominent. This Pokemon can pose a serious threat to so many teams and should rise as such.
