Diancie

Diancie finds its niche in the tier by making use of its useful Rock / Fairy typing to check Dragon- and Flying-types. It can take advantage of its typing, bulk, and decent offensive stats to punish Defoggers like Hydreigon and Moltres and keep Stealth Rock up. Diancie can also act as a cleric, making use of the safe turns it gets on the field to aid its partners. It can also prevent Pokemon such as Latias from setting up on it with its STAB moves or the threat of Toxic. Its typing and bulk allow Diancie to take hits such as Moltres's Supersonic Skystrike. However, its low HP, weaknesses to common types such as Water, Ground, and Steel, lack of reliable recovery, and poor Speed make it easily checked by common Pokemon in the tier like Primarina, Mamoswine, Scizor, and Cobalion. Diancie also doesn't have great offensive stats and can't threaten Steel-types efficiently, meaning it faces competition from Rock-type Stealth Rock users that aren't as passive, such as Nihilego.
