Gliscor

Gliscor has several qualities that make it extremely frustrating for balance and bulky offense teams to deal with. For one, the combination of Poison Heal and Toxic Orb gives it an immunity to status and great passive recovery. Gliscor's Ground / Flying typing offers a myriad of resistances, including an immunity to Spikes and a neutrality to Stealth Rock. When combined with Poison Heal, this essentially makes Gliscor almost entirely unaffected by opposing entry hazards. Additionally, Gliscor has access to a support movepool that most Pokemon could only dream of, featuring Spikes, Toxic, Toxic Spikes, and Knock Off. As such, Gliscor is a fantastic pivot in Ubers, notably taking Sacred Fire from Ho-Oh with ease and setting up hazards on staple threats like Choice Scarf Koraidon and Ting-Lu. This makes Gliscor one of the best Pokemon to take advantage of the lack of entry hazard removal options in Ubers. However, Gliscor is held back by its lackluster stats for Ubers standards; its Defense, while decent, is nowhere near good enough to take on titans like Scale Shot Koraidon, meaning Gliscor has limited use against hyper offense teams. Gliscor is also setup bait for one of the most common threats in the tier, Necrozma-DM, which is only 4HKOed by Earthquake. Gliscor's pathetic Special Defense by Ubers standards leaves it forced out by the vast majority of special attackers.
