Thanks for your patience, Stone Cold. Here's Hydreigon for you. I will look at Ninetales, too, but I didn't want to make you wait any longer.

Hydreigon

Blissey/Chansey are the best Hydreigon counters in the game, there’s simply nothing Hydreigon can do to them.

follow this with "outside of the extremely rare Mixed Hydreigon with Outrage."

. A Specs Draco Meteor to Gastrodon does have the potential to 2HKO, however versus the Scarf and Life Orb Variant Gastrodon can just Recover stall.

Modest LO Hydreigon inflicts 60-71% from Draco Meteor, so I would personally treat it similarly to Specs Hydreigon.

Most Heatran are specially defensive these days, and they have the ability to take Draco Meteors on the switch in, and Fire Blasts activate flash fire making Heatran a decent counter to many Hydreigon types. LO Hydreigon 2HKO's with focus blast while non LO is a 3HKO. With focus blast’s unreliable accuracy, that can often cause a problem.

Calm Heatran cannot do much back, though; Heatran without Roar or HP Ice cannot break Hydreigon's Substitute, and those without Toxic or HP Ice needs to rely on Lava Plume's 30% burn to rack damage on EB / LO Hydreigon. I would probably clarify that Calm Heatran is a solid counter to choiced Hydreigon variants, but is solely a defensive pivot to a non-choiced all-attacking Hydreigon and can only manage to phaze out Sub variants with Roar.

With the main set being the Sub Set these days however, in Rain with Surf, Heatran poses no threat.

• I would remove the rain portion, since Sub Hydreigon still fucks over Heatran with Focus Blast as explained above; Fire Blast is also much more used than Surf.
• "Heatran poses no threat" is a little too extreme and implies the reader being the Hydreigon user. "Heatran's capability in stopping Hydreigon has become limited," is more fitting, imo.

CM Reuniclus is a valuable check that one does not want to be matched up against.

Change 'one' to 'Hydreigon'

Volcarona is yet another threat you stand virtually no chance against given Rocks are spun away, while it can't switch in directly it can come in while Hydreigon is under a Substitute or Hydreigon's special attack is hindered from Draco Meteor and proceed to set up on you with Quiver Dance. Hydreigon can’t outspeed, unless Scarf and even then it doesn’t beat Volcarona so it’s best to switch immediately if that situation occurs.

Here you're obviously speaking from the eyes of a Hydreigon user rather than the Volcarona user. Copy and paste or modify the following post as much as you want to better match the tone of the CC section:

"Volcarona is yet another threat that Hydreigon stand virtually no chance against, given that Volcarona did not take Stealth Rock damage. While it cannot switch directly into Hydreigon, Volcarona can come in while Hydreigon sets up a Substitute or after a Draco Meteor special fall and proceed to set up Quiver Dance. "

• Notice that I removed the Scarf set since I don't think it added much to the paragraph (not saying that Scarf Hydreigon is uncommon, because it is the 2nd most used set outside of your Sub Hydreigon).

Terrakion, Infernape, Gengar, Latios, Latias, and ScarfTyranitar are pokemon that can outspeed and reliably OHKO Hydreigon which is why being under a substitute is important.

Replace the red phrase with, "without a Substitute"

Haxorus can Dual Chop Hydreigon, and Scizor can 2HKO with Bullet Punch. The sun version always beats Scizor while the Rain version cannot, so be wary. Mammoswine is another pokemon that can potentially be a threat, if not for the fact that Ice Shard never OHKO’s, so as long as Hydreigon's HP is high enough Mammoswine can't OHKO.

• Specify Haxorus as Scarfed and move it into the list of Pokemon that are faster than Hydreigon. You can give it a special mention in the following sentence for its multi-hit Dual Chop to break through Substitute.
• Mention Scizor and Mamoswine for their priority. Warn readers that Hydreigon has great bulk and must be weakened before being able to finish it off with Bullet Punch and Ice Shard, respectively.

Cloyster is yet another pokemon which can be troublesome given its focus sash is still intact. With stealth rocks though, Hydreigon outspeeds and can kill with Dragon Pulse/Fire Blast and doesn't have to risk the shaky accuracy of Focus Blast, without stealth rocks Hydreigon normally cannot kill though unless it uses Focus Blast.

• Timid Hydreigon's Dragon Pulse does 110% min to 4 HP Cloyster; Hydreigon does not need to rely on SR damage nor Focus Miss.
• You are writing from a Hydreigon user's perspective (calling Cloyster as 'troublesome'). Copy and paste / adapt the following to better match the tone:
  
  "Cloyster holding a Focus Sash can take an attack and set up Shell Smash. Cloyster could then even outspeed Scarf Hydreigon and even knock out Hydreigon behind a Substitute with a +2 Icicle Spear. Unfortunately, Cloyster's Ice Shard is too weak to overcome Hydreigon's stellar defense."

Breloom troubles Hydreigon if Sub isn’t up, but once again only if it’s the Rain Hydregon. Due to the special defenses of Breloom, even a Draco Meteor from Scarf Hydreigon cannot KO and Breloom can come in with a Drain Punch regaining its HP; however, that's assuming it is the Bulk Up variant of Breloom which tend to run a Careful nature. For the Breloom users who like to run max special defense, Breloom has a chance to live LO Draco Meteor from Modest Hydreigon and almost always lives a LO Draco Meteor from Timid Hydreigon.

This blurb is a little convoluted. You can make it more simpler and clearer like this:

"Specially defensive Bulk Up Breloom can also serve as a check to Hydreigon for Rain teams, which halves Breloom's weakness to Fire Blast. This Breloom can survive a Draco Meteor from Scarf Hydreigon and retaliate with a super effective Drain Punch, which keeps Breloom in decent health. Breloom that are fully-invested in HP and Special Defense has a high chance of even stomaching a LO Draco Meteor from Timid Hydreigon, although a Modest LO Hydreigon would still knock it out most of the time."
