Articuno

Articuno has a unique niche in the metagame thanks strong Ice-type STAB attacks and great bulk. Blizzard allows Articuno to tear through common cores utilizing Rillaboom, Landorus, and Raging Bolt.

Alolan Ninetales is mandatory with Articuno, patching up Blizzard's accuracy and amplifying its bulk and damage output through snow, Aurora Veil, and Helping Hand. Landorus makes for a great offensive partner, threatening Ice-resistant foes like Incineroar, Gholdengo, and Kingambit. Articuno is capable of removing Ground-immune foes like Dragonite and opposing Landorus in return.

Articuno's lack of coverage means the aforementioned Ice-resistant Pokemon such as Incineroar, Gholdengo, and Kingambit are problematic. Opposing weather from setters like Sunny Day and Rain Dance Tornadus are also an issue, as Articuno becomes a lot easier to remove without the added bulk and accurate Blizzards.
