Here is my personal feedback on concepts outside of mine a little bit before deadline for initial submissions, this isn't final council feedback and I'll be discussing with gastlies:
The Faz
As discussed on discord I think this is a solid suite of buffs, gives options without breaking Mandrelec because it still has to commit to 4 moves. Screech lets it slowly break Snorlax but means giving up essential coverage elsewhere, Defense Curl lets it be a very slow physical wall with similar costs, QuakeSlide means giving up on utility moves, Bubble Beam is garbage into anything but Rhydon and therefore a committal choice over using Earthquake to improve a 3HKO to a 2HKO. I approve.

I'm not a big fan of making Corupcake's KO ranges on Chansey/Starmie/Alakazam even better than they already are; I wouldn't veto this but I do think it pushes Corupcake into "too strong" territory with minimal viable switch-ins to Sugar Rush. 90 BP STAB that drops your Special sometimes off an Attack stat higher than Snorlax is a pretty scary idea when the only things that resist it, realistically, are Rhydon, Gengar, Phantom, and itself, and Rhydon and Gengar certainly don't want to take a Fire Blast, especially at -1. I think this tips more neutral matchups like Zapdos too far toward Corupcake as well. Gonna consult with gastlies but I do think this might tip the scales a bit too much.
Phantom buff is fine, we have a few versions that add Hypnosis and I think it's fine to give people options.
Mandrelec buffs feel a little odd, no clue how to feel on these so I'll reserve feedback till talking to gastlies. I doubt they're broken given its Speed but I don't know if I like keeping the coverage so bad and having yet another "walled by Gengar/Rhydon" Swords Dance user (because there's no way you're cramming Bubble Beam + Swords Dance onto one set). Acid Armor feels like it does nothing except into Snorlax - Mandrelec's big issue is its Special, it already has the physical bulk to sit on non-EQ users and you aren't setting up and Rest looping Tauros when a crit EQ does 71-83 and Blizzard does 25-29.
Pineguin not having Bide is just another TM error, we'll fix it and standardize TMs for future submissions.

We do actually have a Kinesis user in OU (Alakazam) but I'm not inherently against this idea. I disagree entirely that Hypnosis is broken and overshadows Jynx; Gengar already exists and Phantom's poor bulk and accuracy make it tricky to land Hypnosis against leads like Surf Starmie, which Jynx performs better against, if still not great. Psychic and Kinesis are fine buffs though and I think this is a fine submission; Psychic giving it some odds against Gengar is pretty cool and you just need one miss to put it in Tauros/Snorlax range. That said, my main issue is that Phantom just... doesn't do anything by itself. No status, no Explosion, no tools besides "forces Jynx out." This improves it but I still can't figure out why you'd lead this over Gengar in most cases.
Mandrelec, meanwhile, I think I would veto this buff on the basis of being too minimal. Amnesia off of 50 Special is a nonthreat when your options are Thunderbolt and Bubble Beam - you're walled by any Grass-type and still will need multiple turns of setup to do decent damage to anything else. I think this is a trap buff that looks stronger than it is, and Slowbro is already struggling enough with a better defensive profile for Amnesia so I doubt Mandrelec has a chance with it.
