The new CoroCoro has revealed three new Megas -- the long-awaited Camerupt, Sharpedo, and Gallade!
It is currently unknown what Ability & stat changes Mega Gallade has (though I'm sure we'll learn soon), but we know that Mega Camerupt has Sheer Force with a decrease in Speed, but boosts in every other stat, and that Mega Sharpedo has Strong Jaw with boosts in all stats.
In addition, Primal Kyogre & Groudon's Abilities have been revealed, and they are called Rain of Beginnings and Land of Endings. They produce an effect called Strong Rain & Strong Sunlight respectively, though it is unknown what they do right now. I think it's pretty easy to deduce that they will activate permaweather, though.
This post will be updated as soon as we learn more info.
One thing I thought of for Mega Gallade is for him to gain a unique Ability that makes slashing moves (Psycho Cut, Night Slash, Leaf Blade, etc.) deal 1.5x more damage -- like a variation of Strong Jaw -- in addition to boosts in Attack & Speed. Perhaps call the Ability Sharp Blade, or something. It'd increase his coverage tremendously, as he has all three of the aforementioned moves, as well as X-Scissor & Slash (though the latter is rather useless in the modern metagame), and he'd effectively gain Adaptability for Psycho Cut. It would also fit him thematically.
Super Luck would also work very nicely, as he has a grand total of 5 moves that have a high crit ratio (Psycho Cut, Night Slash, Leaf Blade, Stone Edge, and Slash), allowing him to land crits 50% of the time with them. Gallade to Super Luck is what Scizor is to Technician.
