>Possibly one of the coolest Mega Evolutions introduced in ORAS, Mega Pidgeot is rendered useless by this change. Firstly, even though all Normal-type moves become physical in this change, Mega Pidgeot isn't widely affected by this, as it uses no Normal-type moves in standard competitive play; however, the move that Mega Pidgeot relies most on, Hurricane, is now physical too, meaning that it has no usable options for STAB moves, seeing as they now deal damage off of Mega Pidgeot's meager base 80 Attack stat. This also means that Mega Pidgeot's far-from-lackluster base 135 Special Attack is now basically useless, as the only special move that Mega Pidgeot keeps, Heat Wave, isn't even a STAB move and doesn't do nearly the job that Hurricane did. At least Mega Pidgeot still has Work Up to boost those physical attacks, if you know what I'm saying!
>With the physical / special split reversion, a lot of Pokémon, Azumarill being one of them, are impacted heavily, and not in a good way. To start off, Azumarill has a Water / Fairy typing; however, both Water- and Fairy-type moves are special, and Azumarill is used (most effectively) as a physical attacker in standard competitive play. Besides that, two of Azumarill's three abilities, Huge Power and Sap Sipper, are both physically oriented, as they both boost Azumarill's Attack in some way. If that weren't enough, Azumarill's most common coverage move, Knock Off, is special too, making its main form of setting up in Belly Drum completely useless. At least you can still use those infamous Choice Specs sets to good use now!
