Overall though I'm somewhat dissapointed in the way the Original Fairies were treated this Gen. Many mono, some not-evolved with a lot of potential (Carbink, Klefki) and no Fairy pseudo legend(opted for another Dragon -_-)
Official hot fudge sundae of the IDF Official Hydreigon of the Pokemon B/W 2 Boards.
Not counting legendaries or megas, Togekiss is likely the best OLD Fairy. It's immune to Dragon/Ground coverage, has great SpDef to tank Fire coverage and can be either supportive or offensive while always being super bulky. Gardevoir and Azumarill I see more as good revenge killers.
Has there been any word on Mismagius being Ghost/Fairy? If yes, that's probably high up too.
I predict Klefki to be just as if not more annoying(due to great typing) as Sableye, tough in no way offensively good. At least I hope it gets the movepool because I like the design and the amazing typing.
Florges is the only 3 stage fairy of the new ones but I'm sceptical because Grass is not too great a typing, even tough it grants powder immunity.
Can't even say anything about Slurpuff and Aromatisse - they both look like your run-of-the-mill cute pokemon, which are typically weak. I really hope Slurpuff is decent at least. Aromatisse has hinted to be a supporter iirc.
