So i think i might possibly be the only person who dislikes the change to Psychic/Fairy. I might also be the only person who used Gardevoir in 5th Gen OU. The thing is, for whatever reason most of the things i used her to check are either part steel or part poison. She used to be a solid counter to Heatran as flash fire made her immune to his stab attack and she could taunt him to prevent him from using Stealth rock/Substitute/Torment/etc. and she could hit him back with a focus blast that may or may not 2HKO. The best heatran could do back is earth power which i dont remember but i think it is a 4HKO, and even if you miss all the focus blast's in the world you could always destiny bond. I dont quite remember but if 2 pokemon have magnet pull then do they cancel out? If not then gardevoir used to be a solid counter to magnezone. Another pokemon, toxicroak, could easily be outplayed by gardevoir. Before they would without a doubt always sucker punch being afraid of the 4x psychic, on which you destiny bond, then on the next turn if they sucker punch, the destiny bond will still be active and if they dont, the psychic will kill.
As for pursuit? Other than weavile, gardevoir is faster than the most common pursuit users and can either focus blast in the case of t-tar, or destiny bond in the case of scizor. Even if the scizor didnt pursuit, they would likely u-turn in which the destiny bond would still kill the scizor. The ironic thing though is that bullet punch was strong enough to OHKO gardevoir even before it became fairy. The only thing that made the strategy work is they didnt know it would kill. Now that Gardevoir is weak to steel... All scizors are going to bullet punch it. While it could just safely taunt ferrothorns before, it now gets one shot by gyro ball. Where before it could easily switch into venasaur, copy its chlorophyll, hit it with a psychic and if it lives, sponge a single hit and then finish it off, it now will get OHKO'd by sludge bomb (this one really matters because with timid gardevoir venasaurs DO sometimes live the psychic dependent on the venasaur's set. Which venasaur was one of the main reasons to use gardevoir previously because it was a straight up monster with chlorophyll: copy chlorophyll->kill venasaur->have insane speed with both taunt and destiny bond to abuse and a really powerful psychic.) Where it could abuse pokemon like amoongus' regenerator before, now it can be hit by sludge bomb (i think now that fairies are a thing, amoongus will be more popular as it deals with azumarill really well now because there isn't much of a reason for it to use ice punch now that it is fairy)
Dont get me wrong, gardevoir being fairy now DOES give it a lot of utility, but it just kind of nerfed the usefulness of its ability as a lot of the pokemon whose ability it can copy and take advantage of now have super effective moves on it.
Btw this only applies to regular gardevoir. I haven't used mega gardevoir so i have no idea how it fares in these situations (in fact mega gardevoir doesn't even have trace so yeah most of the situations i gave don't apply to it.) It being fairy is nice because now it can deal with latios/las fairly easy and yeah it is nice that weaviles now don't have crap on gardevoir, but its just kind of obnoxious because its ability isn't as abuse-able anymore. (im probably forgetting some other situations where it now gets screwed because of its fairy type but i think iv'e delivered my point :| )
Btw feel free to point out any pokemon that it hard counters now with its new fairy type because i can't really think of any.
EDIT: Jesus, that's a giant blob of text i wrote isn't it?
