Ok, I have some problems... Don't take this the wrong way, Admiral Stalfos19 and ZystraL, but I'm really not liking your submissions for the Threat list so far. It's not really what I'm looking for, both grammar- and description-wise.
Admiral, I'll go through your Magnezone entry.
The bane of any Steel-types that pack neither a Shed Shell, U-Turn nor a super effective move.
This statement is slightly pointless. Almost every common Steel-type in OU will carry a super effective move against Magnezone. Bronzong, Kitsunoh, and Metagross have Earthquake, Lucario has Close Combat, Heatran has Fire Blast, Jirachi has Fire Punch, Scizor has Superpower, etc. Some of those carry U-turn (U-turn > U-Turn) as well to escape Magnet Pull.
Magnezone carries a variety of attacks to keep itself alive while waiting for a Steel-type guy to come out of hiding, including Thunder Bolt, Thunder in the case that it's on a Rain Dance team, Hidden Power (coming in either Fire, Grass or Ice), Flash Cannon, Discharge and even Explosion in some cases, and carries a high Special Attack score to back them up.
You do realize that the above paragraph is an entire sentence? There is literally no stops, only commas. When you say that "Magnezone carries a variety of attacks to keep itself alive...", that's not true. Those moves don't keep it alive, they help it sweep. There are a lot of grammatical mistakes (missing commas/colons/semicolons/etc) and spelling errors (Thunderbolt > Thunder Bolt) that need to be fixed.
Magnezone can even carry Magnet Rise to dodge Earthquakes from the likes of Forretress, Bronzong and Metagross... if it can outspeed it, which is hard because Metagross is not only normally faster than Magnezone, but it also can pump a decent amount of EVs into Speed, and will if it decides to use Agility.
I don't know why you went with the "..." after Metagross and you suddenly brought up "if it can outspeed it". Who exactly is the first it and the second it? You then explain that Metagross is normally faster than Magnezone, but it can also pump up more EVs into its Speed. Why exactly would Metagross do that if it already outpaces Magnezone? Also, you don't need the italicized "can".
Magnezone is also a fine choice to dispose of enemy Jirachi if one is sure that it doesn't carry Fire Punch, because it is hard to flinchax to death since it x4 resists it's Iron Head.
Be careful with your "it"s. I have no idea who you are referring to when you say "it", you said that like, 5 times throughout that sentence. Also, "it's" = "it is", so you are essentially saying this:
"...because it is hard to flinchax to death since it x4 resists
it is Iron Head."
That's obviously incorrect.
However, Lucario and Heatran are the only Steel-types that don't mind being trapped by Magnet Pull, and if you take a look at their other types and movepools, there's a pretty good reason for that
Lucario fears Choice Scarf Magnezone obviously, so it does mind Magnezone. Choice Scarf Magnezone is probably the most common variant anyway. I'll give you Heatran. What do you mean by "other types"? They don't have any other types. Also, you're missing a period at the end of the last sentence.
ZystraL, I'll go through your Kingdra entry.
Kingdra is an immensely dangerous threat for a plethora of reasons: it has decent Attacking stats on both sides of the spectrum, it has amazing coverage with STABs alone, Swift Swim cures its less-than-great Speed while boosting one of its STABs and it is almost impossible to out-predict, simply because it can run so many different sets.
"Attacking" should not be capitalized, you aren't referring to Kingdra's specific offensive stats (Attack/Special Attack). What STABs does Kingdra have? You should bring up that Water- and Dragon-type moves provide perfect coverage, only resisted by Empoleon. Kingdra is not impossible to outpredict. Every Kingdra will either be a Dragon Dancer, mixed sweeper, or a standard special sweper. Those can be stopped.
If it holds Rain Dance, you don't know whether to bring in Blissey or Skarmory.
I'd bring in Blissey...
If it uses Dragon Dance, there's still a chance Draco Meteor will kill you.
Uhh... kill what? Why would it have a chance to kill something when I don't even know what it is?
Kingdra is so dangerous, even without set-up, not even the likes of Arghonaut or Revenankh can reliably stop it.
I'd say they can pretty well. I mean, Argho has Recover to recover off Draco Meteor/Outrage and stall out rain. Rev can just use Hammer Arm + Shadow Sneak to end you. It could survive a Hydro Pump or Outrage.
Even Tyranitar, who removes rain and gets a Special Defence boost in the Sand, fears switching into Waterfall.
Sand should not be capitalized. The point of Tyranitar switching into Kingdra is to stop the rain.
Kingdra needs little-to-no support to blow everything to smithereens and is definitely a force to be reckoned with.
No, it can't blow everything to smithereens. It really isn't that invincible.
Ok, so I went through one of each of your submissions and explained the problems. You need to proofread your work multiple times, fix every correction, read it out loud, etc. I honestly hate it when I have to go about fixing stuff like this; it's time-consuming. Also, I suggest you take a look at
this thread, it shows you how to use Pokemon terminology correctly. I really appreciate you guys helping me out with this, but I honestly can't stand it when I have to fix entire descriptions. Don't ever be afraid to ask me or anyone on #cap for assistance, we will help you out.
Please don't take this the wrong way. Thanks.
