I think that Smogon's hurting itself by not outright banning the "big four" -- that is, Deoxys (Attack, Normal, Speed, possibly Defense, but we'll have to see about that once the smoke has cleared a bit), Shaymin-s, Darkrai, and Inconsistent. I've heard things that have said that it is being discussed, but honestly we need some action now. Why are we letting these broken things just sit here and ruin our metagame when we specifically made it so that Phil could make these quick decisions in case of something like this? He ruled on in-game mechanics, so I see no issue with banning them here. Shaymin-s is just awful; even stuff like Nattorei outright loses to Seed Flare + Air Slash, and sometimes it can even be taken down / weakened to the point where next time Shaymin-s comes in Nattorei will lose. Scizor takes a 3hko. You basically need Bronzong, who takes a 5HKO from a Seed Flare + Air Slash. While that sounds awful, remember that Bronzong has to not get flinched three times; one to break a sub, one to weaken it, one to knock it out. Or two, if Shaymin-s lacks a Substitute. But keep in mind that a lot of Shaymin-s carry Hidden Power Fire to knock out those steel types that are being used solely for it, and some are even Life Orb, which make the process even quicker. Shaymin-s also has a ton of opportunities to come in. Roobushin Mach Punch, Gliscor, Hippowdon, Burungeru, etc. While the stats don't suggest it, Shaymin-s is also pretty bulky for a Pokemon with the massive Special Attack and Speed it possesses. It can take stuff like ScarfChomp Outrage in a pinch and throw back Seed Flare to knock it out. Roobushin Mach Punch barely scratches it, and the same goes for Hitmontop Sucker Punch or Fake Out. When you combine this with the ridiculous sweeping capabilities, you definitely have something that is broken.
Next is Darkrai, which, though not as bad as Shaymin-s, is still awful in its own right. With the new sleep mechanic, Darkrai is nigh guaranteed to net one "kill" per game. And that's not even the bad part. STAB Dark Pulse off of 135 base Special Attack, often boosted by a Life Orb? Are you kidding me? How has this thing lasted a week? Fighting priority is the sole thing keeping it from being Kyogre-level broken, since with its blazing 125 base speed, the only things that beat it naturally are Jolteon, Crobat, Shaymin-s, and ability speed doublers. Focus Blast + Dark Pulse offer insane coverage. Dark Pulse boosted by Nasty Plot and Life Orb basically say "Fuck you" to anything that doesn't resist it, and some things that do. Focus Blast nails Roobushin and friends hard. Good luck switching in if you take 70% on the switch. If you make it, good luck doing it again. And again, Darkrai has some decent bulk. Most Mach Punches won't OHKO it. Technician Hitmontop with max Attack can't OHKO without prior damage / Stealth Rock, and can't guarantee the OHKO without 20% prior damage. I'm not sure if Roobushin OHKOs -- probably not, but don't take my word on that. I know from experience that LO Infernape averages around 63% on it. "Weak" attacks like Gliscor Earthquake manage to do around 35%, not enough to stop it from using Nasty Plot and getting that kill.
Deoxys is interesting. Too much of a pussy to take on any priority, but jesus can this thing hit hard. Life Orb Psycho Boost, something that I've seen people use a lot, hits like a goddamn truck. Nothing can survive two hits from this bad boy. With minimal prediction, Deoxys-A can rip through a defensive core without a second thought. Something like Psycho Boost / Superpower (note: this is enough to get three kills per game) / Extremespeed / Hidden Power Fire is beastly. Superpower or Hidden Power Fire cuts through Steel-types like a hot knife through butter. Maybe Specially Defensive Bronzong could survive two Hidden Power Fires, but definitely not three. Superpower is ridiculously strong, and offers some great coverage. The only way to beat Deoxys-A is priority or outspeeding it, really. Psycho Boost is enough to slice up most of the offensive teams. Extremespeed makes it a revenge-killing juggernaut. Kingdra rampaging at 45%? Extremespeed. Scarf Shaymin-s Air Slashing you? Extremespeed. ScarfChomp at 35%? Knocked out. Deoxys-s is another story. It is more for the "REVENGE-killing", since it sacrifices power for the ability to take on Scizor and opposing Deoxys-A and -N. Ice Beam / Superpower / Hidden Power Fire / Extremespeed cuts up a lot of stuff. Save it for the end game and watch it go. Ice Beam is replaceable, I guess, for something to beat Burungeru or other waters, but while Deoxys-A focuses on beating the living shit out of anything with sub-150 speed, Deoxys-S is more about picking off the frail threats that plague offensive teams. Plus it can clean up like nothing I've ever seen before. Deoxys-N is a watered-down Deoxys-A. And i haven't seen too many -D, so I can't comment.
And we arrive at the most broken thing to ever grace this god-forsaken game that we call Pokemon. Inconsistent. Jesus christ, this thing is the stupidest ability ever. You could be up 6-1, and the opponent gets just a little lucky, and bam, you lose. This is terrible players beating skilled players because of luck. Isn't that something that we try to avoid? I've been up 4-1, and had Octillery sweep me. Once it gets the elusive speed / evasion boost, you have virtually lost unless the other player gets insanely unlucky. And the worst part is that he only loses 12% per Substitute with Leftovers and Protect. So if you force it out once, it can come back in later with minimal damage on it. Rinse and repeat until you lose. This is a no skill strategy. It also breaks Evasion Clause, which, now please correct me if I'm wrong here, was voted a clause by a super majority in PR. OH yeah, I'm not wrong. We're letting something out that has a very real, very good chance to be doubling its evasion in one turn. Moves that always hit? Good luck with those. Seed Flare? Have fun while I sweep you. Plus it's inevitable that Octillery gets to +6 in every stat, or enough stats to where it can sweep (+6 speed/special attack comes to mind here). And what resists Toxic / Surf? RestTalk Water-types will eventually get killed by +6 Surf, and are forced to Rest and Octillery's boosts mount. Burungeru can't break Octillery's Substitutes after one Special Defense boost. Even if it goes -1 -> +2, Burungeru is out of luck. Octillery can sweep any team, no matter how prepared. Let's be honest, though, if every Pokemon on your team is built to specifically handle Octillery, what are you doing against the 75+ other major threats that lurk in the shadows...
