Since we're on the subject of type improvements, Psychic is really, REALLY bad. Two of its weaknesses gained significant buffs this past generation, Knock Off is a must on almost every team and the Flying-type does a much better job at handling Fighting-types than Psychic does. Probably one of the worst defensive types as well as being a supremely below average attacking type, the type itself is really a hindrance on dual Psychic-typed Pokémon, and the Fairy-type outclasses it. Here are some ways GF could improve it:
Mind-Altering Moves
-Psychic-types are now immune to becoming confused, encored, taunted or tormented. They still gain stat increases from Swagger or Flatter, however.
This allows the Psychic-type to gain a niche within the metagame. Now that it is outclassed by Fairies, this will help differentiate it entirely, and would most likely help the type garner more attention (because who doesn't want an anti-taunt Pokémon on a team nowadays?). If we're going to go with the logical side of things, it also makes sense in this format. Psychic-types are supposed to be the 'smarties' of all the types. So, why would they be so easily tricked? Overall, this is an immunity not unlike the ones granted to Ghost-types (trapping moves) and Grass-types (spore and powder related moves) this past generation, and would be really beneficial to the once dominant Psychic-type.
Psychic Priority Move
Premonition
Type: Psychic
Category: Special
Power: 40
Accuracy: 100%
PP: 30
Effect: Premonition inflicts damage. If its target attacks the user the turn Premonition is used, Premonition's power doubles and will deal damage before the target attacks.
Because many Fighting-types have Knock Off as a means of destroying their Psychic-type enemies, this move would be useful in helping alleviate this issue. It also gives Psychic-type Pokémon a useful STAB priority attack in a meta where priority attacks are everywhere.
Psychic Freeze-Dry
Distortion Wave
Type: Psychic
Category: Special
Power: 75
Accuracy: 100%
PP: 20
Effect: Distortion Wave deals damage and is super effective on Steel-type Pokémon.
If you look around forums on how to improve the Psychic-type, others have noted that Steel should no longer resist the Psychic-type. "If Ghost and Dark are no longer resisted, why should Psychic remain resisted?" While I don't disagree with this logic, I don't think it's necessary. Ice-types are resisted by Water, but GF decided to give them Freeze-Dry, albeit sparingly. Many Psychic-types have Focus Blast to deal with Steel-types, but are subjected to non-STAB and a glaring accuracy problem. Distortion Wave would help fix this.
Distortion Wave isn't as weak as Freeze-Dry because it doesn't have a secondary effect, and an additional plus is that it is almost as strong as Psyshock; potentially replacing Psyshock on Pokémon who need the Steel coverage (Psychic/Fairy, Psychic/Ice, Psychic/Rock). A downside is that it isn't as strong as Focus Miss even with STAB, but the 100% accuracy definitely makes up for that.

Isn't that move way too strong? It's a buffed Geomancy with no charge turn.
Well, it's a signature move, so the only other Pokémon that could ever use it would be Smeargle. Also, look at Kyosha's stats. The total base stat is 380, and it has terrible Defense, Sp. Defense and Speed stats; enough that it would most likely be OHKOd before even getting to use Sparrow Dance.
