Intimidate Granbull sounds good, especially as it looks so far as the only really physically defensive Fairy (not counting Ubers), so this may provide him niche. Especially when it has really damn good movepool (even it has stuff like Heal Beal, T-Wave, etc.). But yeah, I kind of agree that so far many Fairies look underwhelming. BIG MAYBE goes to Wigglytuff as his support movepool is really damn massive (and Wishes from that 140 base HP sound delicious) and Normal/Fairy is pretty damn good typing, although yeah, I admit it's really specific niche one, but should be fine as well if you ask me.2 more things that I'm noticing:
-There doesn't seem to be many Fairy Types that scream 'top-tier'. I'm sure Azumarril, Gardevoir, Sylveon, Mawile, Mr.Mime, and possibly Clefki (sp.) will all be decent but I was hoping for fairies that would give Scizor a run for its money
