Altaria

Altaria is a good entry hazard control option with a great defensive typing and decent mixed bulk, allowing it to consistently remove hazards. Altaria also has amazing defensive utility, as it can wall powerful threats such as both Paldean Tauros formes, Basculegion-M, and Infernape. Natural Cure allows Altaria to double up as a status absorber, enabling status-hating Pokemon like Diancie, Incineroar, and Substitute Basculegion-M. With Perish trapping sets, Altaria can surprise bulky walls and offensive foes alike that plan to take advantage of it like Bronzong, Porygon2, and Scrafty, and by removing these foes, Altaria can open up its teammates to more easily break through and take on the opposing team. However, utility sets are very passive, meaning many Pokemon such as Toxtricity, Diancie, and Alolan Ninetales can capitalize on it by switching in freely. Additionally, Altaria's 4x Ice weakness means that it must be extremely careful around Pokemon carrying Ice-type coverage like Inteleon, Porygon2, and Milotic as well as common Ice-types like Alolan Ninetales and Avalugg. Altaria requires its Heavy-Duty Boots so that it can reliably use Defog, which forces it to be cautious around Knock Off users it would check otherwise such as Infernape and Scrafty.
