I'm gonna give a complete overview of what I'd like to see in S and A+.
☆ Rank
Mega Salamence - As I've established, this dragon is just too good compared to the S-Rankers. It's got the power, bulk, Speed and versatility to be a literally nearly unwallable threat. Only extremely niche shit can hope to counter it and Mega Salamence usually has sets that get around standard counters, such as the special set dealing with Rhyperior. Its physical bulk after Mega Evolving is
gargantuan and allows it to use almost any physical attacker as set-up bait and forces a ton of switches. Aerilate gives it immense STABs (Return/Double-Edge and Hyper Voice) and all it usually needs for physical coverage is Earthquake. Fast DD, bulky DD, Refresh DD, SubDD, MixDD, physically mixed, specially mixed, purely special... Mega Salamence can pull off all of these sets to fantastic extents. This Pokémon defines the metagame far more than anything else and therefore deserves its own rank. If not, then I'm for a subdivision of S into S-, S and S+, with this one being in S+.
S Rank
Mega Gallade - It may be somewhat slow before Mega Evolving, but after that it has much better power, Speed and physical bulk. 165 Attack combined with Swords Dance and STAB Close Combat is brilliant and all it needs for coverage are Zen Headbutt and Knock Off. It can use its support movepool as well to function as a strong stallbreaker.
Greninja - Amazing attacker with Life Orb, Protean and the newly-acquired Gunk Shot to ruin any Fairy-type's day, no longer countered by Fairies. 122 Speed is still fantastic in this metagame as well, mainly for outrunning Mega Salamence.
Landorus-T - I was advocating for this back at the end of XY, but now I feel like Landorus-T has more than enough reason to rise. Its Scarf set can check all the new physical threats, outspeeding them and crippling them all with Intimidate. On top of that, Ground/Flying is still an excellent typing and it pairs excellently with some of the new Mega Evolutions, including Lopunny, Beedrill, Gallade and Metagross. Overall, its utility, power and ability to be slapped onto just about any team with ease are more than enough to warrant a rise to S.
Mega Metagross - Immense offensive presence thanks to Tough Claws and 145 Attack coupled with a fantastic physical movepool, ridiculous ease in switching in thanks to 80/150/110 bulk, really fast with 110 Speed and can become faster still with Agility.
Thundurus-I - The kami of lightning has gained some new use in ORAS; its 111 Speed is extremely trollish, allowing it outpace Mega Metagross and Mega Gallade, two immense threats. Its ability to spread Thunder Waves is better than ever, looking at the plethora of fast offensive threats. Plenty of reason to make Thundurus-I rise back to S.
A+ Rank
Bisharp - What keeps Bisharp in A+, IMO, is its high power and good typing combined with fantastic STABs in Sucker Punch, Pursuit and Knock Off. All three of these moves have great utility and Psychic-types are running rampant in OU at the moment, so Bisharp serves as a great check to all of them, even a counter to some. Definitely A+ material.
Mega Charizard X - Mega Charizard X has taken a harsh blow in ORAS. Not only does Mega Salamence outclass it in pretty much every offensive role, but Mega Charizard X faces competition from newcomers Mega Metagross and Mega Gallade as physical attackers; it's outsped by all three of these Pokémon and while its burn immunity and role as a supporter on Stall are still really nice, it just doesn't have the same awesome factor that it used to have in XY. Time for this guy to drop to A+ for now, but it could rise back to S once Mega Salamence leaves.
Mega Gardevoir - alexwolf has summed it up pretty well in his post on page 10/11, so be sure to give that a look. Basically, Mega Gardevoir is a fantastic check to some of the new Mega Evolutions and is just as good a special wallbreaker as it's ever been. Its 100 Speed may not be too favorable with the new standard being 110, but this means Mega Gardevoir has even more reason to run Modest over Timid and break its opposition even better. It was already outpaced by quite a few Pokémon and with the new Speed standard, it doesn't feel too pressured and can opt for more power because it's slower
anyway. Mega Gardevoir is one of the best checks to (Sub) Mega Sceptile and Mega Sableye out there, as well as an excellent check to Latios and a full-on counter to SP Mega Latias. Yeah, this dancer should remain A+.
Gengar - Spoop has 110 Speed, the most important number to have at the moment, as well as its awesome Ghost/Poison-type STAB coverage that's become even better with the rising threats. Focus Blast is all it needs in terms of coverage and it can still forgo that when running support moves like Taunt, Substitute, etc. Definitely still A+ material.
Mega Gyarados - Crunch is extremely good for Mega Gyarados and I see no reason as to why it wouldn't run the move. It helps get Mega Gyara past Mega Slowbro, the Eons (and their Megas), Mew and so much more. Waterfall and Earthquake do for coverage most of the time thanks to that 155 Attack, since its moves still hit really hard and Mold Breaker remains extremely useful to break through Clefable and Rotom-W. It can run Taunt over EQ, since Water/Dark has great neutral coverage (as Crawdaunt demonstrated), so it's a surefire threat against Stall teams. Mega Gyarados should rise back to A+.
Keldeo - Another great Pokémon that suffered from the ORAS changes. As stated previously, Keldeo was one of the borderline S-Rankers, but now I feel like A+ is more fitting for it. It's unfortunately outsped by many new Mega Evolutions and Mega Salamence in particular is a pain in the ass for the swordhorse. Still has amazing wallbreaking power and 108 Speed is good, but Keldeo just isn't what it used to be in XY.
Landorus-I - Still a great LO attacker with immense power and a good 101 Speed stat. Its Speed is less stellar than it used to be, but Landorus-I has pretty good matchups against some of the new threats and has a good degree of versatility. Keep in A+, I'd say.
Mega Latias - I'm really torn on this one. I fully understand the arguments to move Mega Latias to S due to its incredible ease at setting up and proceeding to sweep entire teams, but it's really reliant on removal of Dark-types before it can do anything, not to mention it's stopped cold by Mega Sableye. Stored Power sets are walled by Mega Metagross on offensive teams as well, a highly dominant Mega Evolution. I feel like Mega Latias can go to A+ or S, since it does have fantastic bulk and a lot more power, but I don't think it's
quite as good as Mega Metagross or Mega Gallade.
Latios - Despite having the new standard Speed of 110, Latios has decreased in usefulness due to newcomers being able to wall it or cripple it easily; Mega Metagross can come in on almost anything Latios can do and proceed to set up on it or outright OHKO, while Mega Sableye can stall it out of Draco Meteors and proceed to outstall or set up on the dragon. Latios is still great, but not as defining as it used to be, so a drop to A+ makes sense.
Magnezone - Magnezone is at its peak right now. Being one of the very best offensive partners to Mega Salamence and other Mega Evolutions, capable of trapping annoying Steel-types and dealing excellently with unboosted Mega Slowbro thanks to its brutal Thunderbolts coming off of 130 Special Attack, it definitely has a lot going for it as the metagame currently is. Its many resistances are still incredibly useful as well, allowing it to be partnered with a huge slew of Pokémon.
Mega Sableye - Rupee troll deserves to be in A+ because of its wonderful stallbreaking capacities, not giving a shit about status thanks to Magic Bounce, having a great pre-Mega Ability in Prankster that still works on the first Mega Evo turn, much better 50/125/115 defenses and the ability to run multiple trollish sets. It's also the only foolproof Mega Gallade counter, which is pretty big considering how dangerous the swordsman is. Not to mention, this thing makes Stall its
bitch. A+ for Sabes.
Talonflame - Its revenge killing potential is greatly appreciated to let bulkier attackers have an easier time shredding through teams. Priority Brave Bird has gained even more use right now, looking at some of the new Megas, like Gallade, Sceptile, Lopunny and Beedrill. Still pretty strong as a RKer and definitely retains its overall usefulness, so it's got enough reason to stay in A+.
The Pokémon I haven't listed that currently
are in A+ should drop, IMO. Either that or I don't really know how much the new meta has impacted them, hence why they're not listed.. I'll be explaining why they should change rank when discussion about A and A- begins, but this is my big post on S and A+. If there's anything you'd like to add or disagree with, I'd love to hear supportive arguments and counterarguments alike.
Kyuzeth out.
