Staraptor (B-) -> B+ | Speaking of
actually underrated Pokémon, Staraptor is another fantastic wallbreaker to add the repertoire of rising stars in OU ever since Aegislash packed its stuff and left for the gods. Seriously, this thing can hit brutally hard when Banded, which is easily its best use. As people before me have pointed out (and I'm also saying this out of personal experience), Adamant Band Raptor just hits brutally hard with STAB Brave Bird and Double-Edge, shredding everything that doesn't resist it. Here's a small example:
252+ Atk Choice Band Reckless Staraptor Double-Edge vs. 252 HP / 252+ Def Rotom-W: 252-297 (82.8 - 97.6%) -- 68.8% chance to OHKO after Stealth Rock
This right here is why Staraptor runs Adamant; that extremely high power output makes a huge difference between 2HKOs and OHKOs and all you need is to set up your Rocks and have Staraptor maul everything. It pairs excellently with Talonflame and Mega Pinsir to form a Flying Spam core, Staraptor crushing all the walls that need to be broken down to allow Talonflame or Mega Pinsir to sweep safely. As a last positive note, Staraptor attains perfect coverage between Normal/Flying/Fighting and in conjunction with its insane power, it's extremely difficult to switch in on. What keeps bomb burd down from being a total annihilator are its weakness to SR, its above-average Speed stat of 100, its relative frailty (85/70/60) and its common weaknesses to Electric-, Rock- and Ice-type moves. With Aegislash out of the picture, though, Staraptor has become a whole ton more impressive in OU.

Mega Gardevoir (A-) -> A | You thought Mega Heracross was a nightmare to Stall? If that's what you thought, then Mega Gardevoir would be the poltergeist haunting it! Seriously, this Pokémon has become even more amazing than it already was. 165 Special Attack is absolutely fantastic and Mega Gardevoir has just the right movepool to maliciously abuse the living fuck out of it. Its signature Pixilate Hyper Voice has 175 power counting STAB and Pixilate, but its Fairy-type and ability to bypass Substitutes is just mind-blowing. This move alone makes Mega Gardevoir ridiculously hard to switch in on, but this dancer has access to STAB Psyshock to hit physically weak Pokémon and provide additional coverage. The third main move on Mega Gardevoir is Focus Blast, which, while inaccurate, allows it to slay most of the Steel-types that tend to annoy it, including Heatran, Skarmory and Mega Mawile. Since Aegislash has left, these three moves provide perfect coverage in OU and leave room for another useful move to add: Calm Mind allows Gardevoir to raise its Special Attack to insane levels, while giving it notable Special Defense to take hits on the special spectrum; Taunt gives Mega Gardevoir the ability to completely lay waste to Stall teams; and Will-O-Wisp lets it cripple physical attackers for a teammate to set up on or catch said attackers by surprise on the switch to live a physical hit. Additionally, stat-wise, Mega Gardevoir has a wonderful Special Defense stat of 135, giving it notable special bulk that can be augmented by Calm Mind, as mentioned before. 100 Speed is a good Speed tier in OU and since several other base 100s often don't go max Speed, Mega Gardevoir can easily run a Modest nature to make its power simply absurd.
With all these fantastic advantages, Mega Gardevoir does have some notable flaws. Firstly, its measly base 65 Defense gives it no physical bulk if not using Will-O-Wisp and leaves it prone to being revenge killed; Talonflame is the worst offender, as it's immune to burn courtesy of its own Fire-type. Additionally, 100 Speed is good, but not fantastic and leaves Mega Gardevoir outsped by key OU threats, such as the Eons, Thundurus-I and Landorus-I. This issue can be fixed by using Sticky Web, however, and Mega Gardevoir is easily one of its best abusers in the OU tier. To summarize, Mega Gardevoir is a massive threat due to its general unpredictability, jaw-breaking special power and being extremely difficult to directly switch in on.
