Sheps you forget, gamefreak doesn't care about the meta. Predictions are
Fairy super on dark as well as dragon. We know fairy is not resisted by dark as hydregion in the video takes the hit super effective IIRC.
Fairy may resist dark, but its more likely to be neutral.
I'd love fairy to resist dragon but it probably won't.
Fairy may be weak to Dark (both super against each other), and probably resists fighting. Fire grass water for neutral, and gardevoir to potentially become a decent pokemon. Azumarill to get a huge boost as it gets a second STAB it can use and probably more moves. Fairy hitting dragon means it can run STAB over ice punch potentially, which could OHKO dragonite through multiscale, hit haxorus for an OHKO which I don't think ice punch does, and be better for switch predictions ETC.
Jigglypuff will still be crap but I will put eviolite on it and use it anyway. With sing.
