Mega Medicham: A to A+
obliterates much of the meta with its insane attacking power, nice movepool options so things like clef and slowbro cant even reliably check it defensively, access to [double] priority so mega evolving, chip damaging, and sand stalling is super easy while remaining competitive vs fast offense, and pairing it voltturn and playing competently with it can easily net you at least 2 kills per match. also completely tears up fatter teams that lack reuniclus, mew, msab, and more fat shit like this, but most of them are either relatively uncommon or bad (looking at you cofag and cresselia). also please dont use that bullshit "it doesnt preform well vs offense" excuse because look what happened to hoopa-u (albeit it had 0 switch ins at all but at least medi has a better speed tier + [double] priority). getting chip damage on its checks isnt even hard too because you can just easily spam voltturn and wear down the opp's team pretty quick, forcing repeated heals and putting them in range of one of medi's attacks.
Mega Sableye: A to A-
incredibly easy to chip down w/ stuff like scald and lava plume, stray volt switches from rotom, and sand so you're forced to heal constantly, many hazard users have adapted to its presence (sd chomp/lando, clef, dazzling klefki), and it gets chipped pretty easily if it switches into them anyway, and it is not even a reliable counter to mega medi because it gets chipped so easily (you let it get down to like 70% and you die). ofc its typing and abilities are amazing, but it isnt difficult to push it to its limit at all. its also bait for things like keldeo, which just leads to amoongy getting burned, which blows or tg + rd manaphy, which can set upfor free and blow back your squad, especially if chansey is low/it got pursuit trapped or something.
Jirachi: A- to A
can provide so much for teams (pivot, hw user, sr user, voltturn user, and wish user), checks big threats such like latios, clefable, and mega diancie, iron head flinches are super clutch (seriously being able to beat lando and excadrill 1v1 with just flinches is retarded), and its nice bait for its common switch ins (thinking about heatran, etc), making it so it can just click uturn and bring out the keldeo/medicham/heracross to snap their neck.
