Funny to see how Gliscor is sending everyone to UU.
Loyal trio: weak to Ground (the cool bird has other problems too though).
Chomp: Direct competition as SD sweeper and hazard setter.
Heatran: Very good check to it (had already many problems before).
Clodsire: Not only direct competition, but also free switch-in to it.
Sandy Shocks: Forced to Tera to do progress vs Gliscor (though its a good Tera for it).
Moltres: Free switch-in to it (as long as its poisoned).
Garganacl: Good check (Clefable was the biggest one though).
Amoonguss: Again, free switch-in.
Mandibuzz: Read above. At least this one can beat SD sets.
Also, Tusk, while solid vs Gliscor, has also decreased usage A LOT . Lando-T and Glowking suffer too, Ting-Lu (which in my opinion has always been garbage) its at 5% as well.
This is something I actually expected long before Gliscor was released. Even if it survives the Ban hammer (hopefully not. in my opinion it has to be the next target), it has for sure impacted the meta a lot.
