alright, tested the drops, some more than others, and will add my thoughts on them on this thread, from less tested to more tested. huge post alert.
goodra: A- rank - nice resistances, amazing special defense and good movepool makes it a good pivot against a lot of stuff, and it can counter volcarona with rock slide. 110 sp.a is no slouch either, it does heavy damage with draco meteor and even learns sludge wave for fairies and fire blast for steels. but it's slow, has a terrible defense and is basically limited to being a tank, i think. i haven't used it much though.
infernape: A rank - honestly i have no idea why this was OU for so long. it's very very bad there, and it's not THAT good in UU. huge, very huge movepool and good offensive stats make up for a relatively hard to predict mon. can be tailored to lure and kill/weaken specific mons like using gk for slowbro or SD for mew, but outside of that, it's still easy to revenge kill, and can be hard checked by tentacruel, for instance.
alakazam: S rank - imo this guy is really really really good, but not broken. focus sash revenges literally every common setup sweeper, with exception of the probably BL volcarona and cloyster and brings balance to the metagame i think. (i wish it was here during mence test, would be a good check and maybe prevent its banning). even if the foe does not bring a setup sweeper, it still has high special attack, a very speedy encore and good coverage with psychic - shadow ball - maybe focus blast, but that is a very shitty move, other options are energy ball and dazzling gleam.
alakazam-mega: S rank, possibly BL - mega zam is incredible, it was absolutely destructive even in OU. but since it dropped i'll talk about it: basically you have a deoxys-a with trace, although it lacks psycho boost and 400 attack superpower, but with trace! yes, trace is like REALLY good. list of funny stuff to trace:
-flash fire from arcanine/chandelure/houndoom (risky if they predict you)
-levitate from flygon
-natural cure from blissey or rade
-sheer force from darmanitan/nidos, (trust me: you DON'T WANT to eat a sheer force psychic from 493 sp.atk)
-speed boost from sharpedo/yanmega
-analytic from magneton/starmie/porygon2
-adaptabilty or download from porygon-z
-regenerator from slowbro/amoonguss/alomomola/mienshao
-magic bounce from xatu
-prankster from whimsicott (very useful if you run encore or taunt)
-this list is huge as fuck already
then, with a coverage of psychic/focus blast/shadow ball, and running modest because it can afford to run it as it has mega aero's speed, it 2HKOes THE WHOLE METAGAME (except for blissey, but you can run psyshock over psychic for that). its problem is that it's still relatively easy to revenge with scarfers or sharpedo or priority, or trap with pursuit from the likes of escavalier, and you can always run spiritomb or sableye to counter it if it threatens your team too much, and it takes up a mega slot; but tbh this is the best mega evo of UU, (with mega aero being the second best by a tiny margin) so i don't think the argument that it takes up a mega slot is valid for it. i think it might be banned, but only time will tell.
volcarona: S Rank, probably BL - bulky QD with roost is imo the most broken thing atm. it needs a couple of quiver dance boosts to completely wreck everything barring uncommon things like specially defensive arcanine with roar or toxic and av entei. and it's actually VERY EASY for it to get up multiple qd boosts, seeing that slowbro, mew, florges, forretress, and a lot of stuff cannot even touch it without running shit moves like toxic. i am yet to try offensive qd since after it goes +1 it reaches almost the same sp.atk as a +2 bulky qder, and with LO it must hit much harder, but imo it's too frail and more susceptible to being revenged or picked off by prio users.
lucario: A+ rank - bipedal dog is actually very manageable, having a lot of troubles in consistent sweeping the opposition. tbh i would rank it in A-, but what makes it go A+ for me is the viability of its sets. SD is imo the best one by far, because +2 close combat OHKOes everything and +2 extremespeed OHKOes most things that can revenge it; however, it's kinda easy to wall with slowbro or physically defensive mew, even if it has crunch it'll get statused, not to mention it'll fail breaking florges, the most common poké; and if it opts to run iron tail, it makes the job easier for slowbro, volcarona and not to mention the accuraccy. i found the NP set to be pretty good, i was using NP - aura sphere - dark pulse - flash cannon, and while it beats the annoying pink core, it's even easier to revenge kill, as it has only 306 speed; vacuum wave is weak as shit and it still doesn't prevent a lot of stuff from revenge killing you (cannot OHKO flygon at +2, even if running modest). i tried specs too and it's a very good lure, since slowbro or hippowdon are usually the first stuff to switch into lucario, and both take huge amounts of damage if you predict correctly. agillity would be the other viable set i think, but imo it just seems too bad.
PS: mega aerodactyl checks literally EVERY SINGLE ONE of the new drops, solid mon.
