This (http://www.smogon.com/forums/showpost.php?p=2991398&postcount=30) is proper PokeGrammar according to the conventions listed here and is therefore not an error.
Once Darkrai has put a Pokemon to sleep and has activated Sleep Clause, it is much easier to check. Fighting Arceus is Darkrai's only true "counter", even after Sleep Clause has been activated.
Ho-Oh is also a good counter to Darkrai after its ability to sleep opposing Pokemon has been used up. Thanks to Ho-Oh's massive Special Defense, it does not fear a boosted Dark Pulse from Darkrai as much as other Pokemon and can retaliate with a powerful Brave Bird that can OHKO.
EVs
4 Atk / 252 Spe
Leaf Storm vs. 252 HP / 0 SpD Uxie - 66.4% - 78.2% (2HKO with Stealth Rock)
Leaf Storm vs. 0 HP / 0 SpD Swellow - 97.3% - 114.6% (OHKO with Stealth Rock)
Leaf Storm vs. 244 HP / 0 SpD Spiritomb - 91.7% - 108.3% (2HKO with Stealth Rock, chance of OHKO)
Leaf Storm vs. 0 HP / 0 SpD Houndoom - 61.6% - 71.6% (2HKO with Stealth Rock)
Leaf Storm vs. 252 HP / 100 SpD Clefable - 66.5% - 78.7% (2HKO with Stealth Rock)
Leaf Storm vs. 252 HP / 252 SpD Steelix - 78% - 92.1% (2HKO with Stealth Rock)
Leaf Storm vs. 248 HP / 0 SpD Milotic - 124.2% - 146.6% (guaranteed OHKO)
Leaf Storm vs. 212 HP / 0 SpD Torterra - 88% - 103.6%
Leaf Storm vs. 4 HP / 0 SpD Mismagius - 108% - 127.5% (guaranteed OHKO)
Leaf Storm vs. 252 HP / 0 SpD Mismagius - 79.6% - 93.8% (2HKO with Stealth Rock)
Obviously, slow special sweepers are the best recipients of both Speed and Special Attack boosts. Venomoth, though rarely seen, is able to do a lot of damage with boosts, thanks to Tinted Lens. Other noteworthy recipients include the partners listed in the previous set, along with the likes of Magneton, Espeon, and others.

When it mention's swamperts niche use of rindo berry, it says it can strike back with Magic Coat when it is supposed to say Mirror Coat.
it also says that swampert can phaze out something with hidden power ice; shouldn't this be grass?
http://www.smogon.com/dp/pokemon/kangaskhan
should be Physical Attacker since it's referring to a set.
http://www.smogon.com/dp/pokemon/mismagius
This sounds awkward. I think the "not" in between will and break should be removed.
http://www.smogon.com/dp/pokemon/mamoswine
in team options it mentions this obviously a mistake from when mence references were changed.
http://www.smogon.com/dp/pokemon/grumpig
In Grumpig's "Counters" section, Honchkrow is mentioned in the first paragraph, the one that starts with, "In UU," This implies that Honchkrow is UU, when it is now BL.
http://www.smogon.com/dp/pokemon/absol
This is the first sentence of the Absol analysis:
Absol's amazing base 130 Attack stat coupled with Swords Dance and the strongest priority move in the game makes make it a devastating sweeper against those who aren't prepared.
Incorrect subject-verb agreement.
http://www.smogon.com/dp/pokemon/metagross
Either set "Trick + Iron Ball" needs to have the "Ability" category removed or all the others need it added. I think removed is best since Metagross only has the one ability.
http://www.smogon.com/dp/pokemon/abra
The goal of this set is to use Abra's awesome power, while attempting to get rid of its glaring weakness to priority. (First sentence in the SubAbra set, not entirely sure if the comma is necessary there, it looks awkward to me)
One of the best would be Munchlax, who isable to shake off a couple of Abra's hits and kill it with any of its attacks. (Second sentence in the Counters section)
The Steelix analysis page (http://www.smogon.com/dp/pokemon/steelix):
Steelix doesn't have a Choice Band set (not anymore, anyway).
Dragon Dance Crawdaunt has Crawdaunt spelled "Craudaunt".
http://www.smogon.com/dp/pokemon/alakazam
On the set "Aggressive Lead":
Spiritomb doesn't have any weaknesses.
http://www.smogon.com/dp/pokemon/metagross
On the mixed attacker analysis, the EV's for speed are listed as 4 more than possible, giving a total of 512. The analysis refers to a speed of 209, which is the speed with the correct speed EV's of 132.
I have fixed this. Sets shouldn't list both abilities if both are viable.http://www.smogon.com/dp/pokemon/houndoom
at lead set ability is linked to http://www.smogon.com/dp/abilities/early_bird__flash_fire instead linking to both abilities separately.
Also same thing here: http://www.smogon.com/dp/pokemon/abra with choice set.
I have fixed this.www.smogon.com/dp/pokemon/shedinja
Under the Baton Pass set, where the author describes the use of Heal Block, he says "and other healing more". Based on the context, this should be "move".
I fixed this.In the Special Life Orb analysis of Flygon, a sentence reads, "For example, come in on a Pokemon such as Starmie (who outspeeds Flygon) and threaten an KO with U-turn ThunderPunch. It should read, "For example, come in on a Pokemon such as Starmie (who outspeeds Flygon) and threaten a KO with U-turn or ThunderPunch."
Also, in the Trick Iron Ball set for Metagross, a sentence reads, "With poor prediction, this set will face difficulty against Heatran, while Earthquake can keep it at bay, it can easily come in on a Meteor Mash and proceed to pick off Metagross." It should be separated into two sentences: "With poor prediction, this set will face difficulty against Heatran. While Earthquake can keep it at bay, it can easily come in on a Meteor Mash and proceed to pick off Metagross."
I finished with Bastiodon - Butterfree, a total of 10 typos and incorrect statements.
http://www.smogon.com/dp/pokemon/bastiodon
--In the first sentence of the Offensive Metal Burst set, it incorrectly states that only Bastiodon and Aggron can learn Metal Burst. Dialga can as well. This should be fixed by saying that Aggron and Bastiodon are the only non-Uber Pokemon to learn Metal Burst.
--In the second paragraph of the same set, it says "Curse and Metal Burst is a fabulous combination". This is fixed by either saying "Curse + Metal Burst is a fabulous combination", or by saying "Curse and Metal Burst are a fabulous combination."
--In the Opinion section, near the bottom, it says "giving you a 4x Ground and Fighting weakness". This should be "giving you 4x Ground- and Fighting-type weaknesses."
http://www.smogon.com/dp/pokemon/beedrill
--In the Agility set, near the bottom, it says "will demolish Roc-k and Steel-types." This should say "will demolish Rock- and Steel-types."
http://www.smogon.com/dp/pokemon/bibarel
--In the Tauntarel set, last sentence, it says "guarantee an OHKO." This should be "guarantee a OHKO."
http://www.smogon.com/dp/pokemon/blaziken
--In Other Options, first sentence, it says "As Blaziken has viable sets". All Pokemon have viable sets, and Blaziken has a ton, so I think the author meant "As Blaziken has many viable sets".
http://www.smogon.com/dp/pokemon/blissey
--In the OU Counters list, for Machamp, it says "Machamp can easily switch into any Blissey set with ease." "Easily" and "with ease" are redundant, so just pick one and remove the other. I personally like "with ease" better.
http://www.smogon.com/dp/pokemon/breloom
--In the last paragraph of the Choice Scarf set, it says "neutralising threats". Now, neutralising may be the British spelling, and is technically correct, but the use of American spellings throughout the rest of the article makes this sound awkward.
http://www.smogon.com/dp/pokemon/bronzong
--In the Trick Room set (not Off. Trick Room), second sentence, the "B" in Gyro "B"all needs capitalized.
--In Team Options, third paragraph, it says "who causes Bronzong problemsas all it can do". There needs to be a space between "problems" and "as".
That's it for the B's that I saw.
The only Pokémon are not OHKOed are heavily defensive, such as other Groudon or Giratina, and thus cannot do much back.
