Covering the new megas..
M-Beedrill gets Aerilate, which is neat, I guess.
M-Pidgeot gets Normalize...Hurricane wasn't STAB already.
M-Slowbro gets Shield Dust, so no Scald burns or flinching, which is cool.
M-Steelix gets Sand Rush, to hit max speed of....280..
M-Sceptile gets Limber, so either way, fuck yo T-Waves.
M-Swampert gets...Symbiosis. You probably don't even know what that does, but it has a chance to pass an item to an ally..
M-Sableye and M-Diancie get Magic Guard, which isn't too bad.
M-Sharpedo gets Sturdy...any ideas on what this can do guys?
M-Camerupt gets Shell Armor, so no more crits, yay.
M-Altaria gets Plus, which is really a Minus.
M-Glalie gets Regenarator, which is pretty bad when thinking about Glalie's bulk and typing..
M-Salamence gets Aftermath, so maybe a Salamencite unban?
M-Lati@s still have Light Metal, so yay.
M-Rayquaza gets Desolate Land, which is fitting, since it made Ubers desolate.
M-Lopunny gets Serene Grace, which sucks but eh.
M-Gallade gets Insomnia, which is a nice upgrade.
M-Audino gets Heatproof, which actually would make it a decent ZardX counter in OU.
And finally...
M-Metagross gets Toxic Boost, which really helps it out, as it now is the ultimate Poison switch in, being immune to any sort of poison ain't enough, fuck the hackers, am I right?
So overall, most new megas got fucked over, mainly Metagross, Altaria, Swampert, and Lopunny, but a few actually benefited from this, like Audino, Gallade, and maybe Mega Salamence could be unbanned?
By the way, with the new abilities, Pressure is no longer turned into Protean, it is turned into Primordial Sea. And what can use this ability, Zapdos, Raikou, Suicune, Wailord and Bisharp. Not a lot of options, but still things to consider.
And I am going to review what I think is good.
Infernape now gets Justified, making it the ultimate Bisharp counter.
Sudowoodo gets Reckless, but no Head Smash

Wait, couldn't Lickilicky hit you with two CB Explosions thanks to Parental Bond?
Ya know, Pokemon with Pickup getting Pixilate would be pretty cool, but all of the viable ones are Normal types..
People talking about Exploud getting Speed Boost, what about Mr. Mime, it is pretty interesting with Baton Pass, but only if BP chains weren't banned..
Noivern and Yanmega gets Gale Wings from Frish, so that's cool.
M-Ampharos may be a loss to Ampharos' general viability, but I feel Poison Heal from Plus makes up for that.
Chansey can abuse No Guard Sing and Dynamic Punch lol
Overall, a pretty nice meta, sucks that a few great abilities can't be played due to the sole owners of abilities before them being banned, like Unaware only avaliable to Reshiram and Kyurem White and Filter only avaliable to Xerenas. I mean, there is a good trade-off for this, being Yveltal being the only Pokemon to get Defeatist....wait....
UNBAN YVELTAL!
