This may just be favoritism, but I feel Mega Absol should move to C+/B-.
With Mega Absol's new access to Knock Off and Sucker Punch, it gives it two great Stabs that it really needed to function . It has plenty of utility, being able to function as a Mixed Sweeper, or the most popular set being straight up physical. Since Mega Absol also get's access to Superpower and Play Rough, it helps out with it's main threats of Fighting Types and Bisharp. Also, being granted with a base 115 Special Attack stat, the mixed set can hit pretty hard too, since it get's things like Shadow Ball, Ice Beam, Fire Blast, Thunderbolt, Dark Pulse, and others.
Also 115 Speed isn't bad at all, with a beneficial nature and max investment, it outspeeds Lati@s, Celebi, Jirachi, Mew, Mega Gallade, Gengar, Keldeo, Thundurus, and so on and so forth. While Speed Tying with Raikou, Starmie, and others.
Feel free to discuss.
Just a few things before I start off:-
-Mega Absol has had Sucker Punch and Knock Off since Poké Bank. If it didn't it'd be downright unviable.
-Don't use Dark Pulse, Thunderbolt or Shadow Ball. Please.
Anyway, I really don't think it fits well into this meta and I feel people are overrating it's new ability to have both Knock Off and Play Rough quite a bit. While this is of course a buff, it really seems to be the only reason people have advocated a move up and I have to disagree with it because it appears to ignore every other metagame change. For one, you have Mega Metagross. Currently ruling the metagame and on about 14% of all teams if the usage stats are to be believed, Mega Metagross at most takes 80% from Absol, and that's from a max roll Sucker Punch. It then KOs back very easily with... any move really. This is problem number 1: the metagame has taken up a more bulky offence feel with the arrival of ORAS. This means Mega Absol finds it difficult to get off a KO at all, and if it can't, it dies to literally any move.
Problem number 2 is that there's a ton of fairies now. Mega Diancie and Mega Altaria, not to mention the return of Mega Gardevoir pose a great threat to Absol who has no moves it can really hurt them with unless it runs Iron Tail (lol). Even Mega Gardevoir only takes a maximum of 84% (sucker punch) from Absol.
Problem number 3 is that the set that's been hyped up the most is Swords Dance. If you're nominating it based on another set than SD please feel free to ignore this; but this is the set touted the most. When does Mega Absol get the chance to set this up? Looking at the S and A ranks alone, it either fears a very hard hit, a scald burn or being outsped and wrecked by just about anything there. Gengar, Mega Sableye and Celebi seem to be the only things it can truly set up on, and it might force out Keldeo and Mega Gallade, but honestly half the meta shreds this thing to pieces. Hell, just setting up a
Mega Evolution is a problem for largely the same reasons, in addition to a lot more thing outspeeding you you could usually beat with coverage such as Gallade and non-scarf Keldeo.
Problem number 4, there's been a big speed creep with ORAS. While this seems in contradiction to Greninja's banning putting pressure off for, say, base 110s and base 115s, there's still a lot of things Absol has to worry about being outpaced by -- naturally faster Megas like Sceptile and Beedrill have been introduced, faster threats that have risen since Greninja's ban such as Tornadus-T and Weavile have popped back up, not to mention Mega Aerodactyl being very good at the anti-meta job right now. There has also been a great resurgence of Rain, and Mega Swampert only uses Absol as set-up fodder. Finally, any scarfer or D-Dancer has nothing to fear from Absol right now, and rarer boosters such as RP Diancie, RP Metagross and Sharpedo also exist.
Finally, Problem number 5, opportunity cost. This is a problem many lower-tiered Megas are facing right now thanks to ORAS bringing us like 17 new ones or something, and you have to ask yourself on which team will Mega Absol truly be the best fit in a meta invested with fairies, bulky offence and priority? It's frail, it didn't get anything much in the ORAS metagame shift and it only got more things that threaten it.
If anything, I feel Absol should
Stay where it is. This meta is not kind to it in the slightest, Play Rough alone is not enough of a buff and it is in no way consistent enough to move up to C+, never mind B-. I don't mind it staying where it is but it's really not good enough to rise.
Don't most sceptiles run energy ball/giga drain so he can stay in and not be set up bait, scept hits with leaf storm and has to switch while serp doesn't.
I was comparing Leaf Storms in the whole 'comes in hits shit gets out' scenario; some Sceptile fill this role while others prefer a Sub, which by the way really fucks over stall. Serperior's Leaf Storm is of course more powerful than Mega Sceptile's Energy Ball, but the point here was to show that Mega Sceptile can come in and do a lot more damage than Serperior can. In addition there's also Dragon Pulse which is of course more powerful than Serperior's.
