What set is the "best" set for this meta for Mega Aerodactyl, as far as EVs, nature, moveset, that you have found?
I would imagine 252 adamant attack, and enough speed to ensure it gets over that 427 benchmark set by the 252+ speed base 145Mons.
Just on a few calcs I'd run.
Adamant base 150 speed maxes out at 399 speed. To outspeed Timid Sceptile and Jolly Beedrill you have to run Jolly yourself.
Is... is that a successful attempt at a MegaMence counter?
It's a strong check. It can't come in on +1 Return because it's outsped after a DD. It can switch-in on the DD, but not after. That's also assuming Mence isn't running Dragon moves. I know it's not common right now, but Dragon STAB moves are still out there. Bulky DD Mence sets also survive the confrontation, although not without some damage.
I think the reason people don't consider MegaAero has other reasons:
Do you realize that out of these six megas(Beedrill isn't weak to Ice) three of them are weak to one of your STAB? And that Altaria and Latias are bulky enough to shrug off Ice Fang with little conseguences?
STABs hit Mence, Beedrill, Sceptile and Pidgeot super effetctively, so you're not going to be using Ice Fang against those anyway. Heck, even against Mega Altaria, Hone Claws Aero only leaves 10% on the table using Stone Edge over Ice Fang. STAB Stone Edge comes close enough damage-wise, and after Hone Claws the accuracy difference doesn't mean much. If I need to hit the Lati@s Megas, you might as well run Crunch, that hits them for more damage while allowing you to hit Slowbro and Metagross as well. It's moves aren't limited by what can take advantage of Tough Claw either. Stone Edge and Earthquake are both perfectly useable on Mega Aero, and they don't get the boost. Hone Claws is also a great move for Aero because it patches the accuracy on every move perfectly after one boost. 4 attacks Mega Aero really isn't that good tbh. I really only run Hone Claws+3 attacks and Hone Claws+Roost+2 attacks, and accuracy isn't really an issue on those sets.
Low Kick 2HKOs Empoleon.Here are a couple of mons which are pretty anti-meta right now.
Empoleon @ Leftovers
Ability: Torrent
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
- Stealth Rock
- Scald
- Defog
- Roar
With Greninja being one of the most threatening mons in OU thanks to gunk shot move tutor in ORAS, Empoleon becomes one of the best defensive checks for it. Thanks to its typing and very good special bulk, it's reliably able to take any hit from Greninja, the most threatening move from it being grass knot which does 27-32%. Seeing as grass knot is sub optimal at the moment anyway, Empoleon shouldn't have anything to worry about when facing it. Emp can also check with a number of the new threats including cm mega latias, cm slowbro, diancie, sub dd salamence and a few others.
Spiritomb @ Leftovers
Ability: Infiltrator
EVs: 252 HP / 4 Atk / 252 Def
Impish Nature
- Foul Play
- Will-O-Wisp
- Pain Split
- Pursuit / Filler
Physically defensive spiritomb is a really nice check to sub dd salamence, gengar, mega latias and a load of physical attackers in general. With its infiltrator ability, tomb can easily pick sub dd salamence off with a will-o wisp or with a foul play after taking any one hit. Many of the core using mega latias focus on using fighting types to pressure dark types but by virtue of tomb's ghost typing, it can stay as a check for mega latias without having to be worried about getting nailed by a fighting move. With gengar being one of the most powerful mons at the moment, the fact that the most gar can do is hit tomb for neutral damage is really nice as well and nailing it with a pursuit is really really easy. There are also a number of powerful physical attackers at the moment which tomb can blast with a STAB foul play such as gallade, scarf landorus t, swampert, beedrill etc. I'm not saying tomb is a fantastic mon but i think it has a couple of good niches within the oras metagame.
