While I'm on here, I'd also like to start something up that I discussed with a friend on Swift Swim Kingdra. I'm not entirely sure if it makes it overpowered in the OU tier, but I've seen alot lately bunched up with Politoed, and being able to DD and sweep quite a bit. I understand how there are clear counters like Ferrothorn, but if it powers up (it has few tools at it's disposal to do so) it can 6-0 a team with mostly ease. Why do I say this? Well, Kingdra, with it's typing, only has a weakness to Dragon types. Now, I looked up the damage calculations, and found out that a Banded Dragonite with extremespeed (because otherwise Kingdra would outrun you) deals a max of 181 damage to a kingdra with no Defense EVs. This means that, since dragon moves are the only other thing that stand a chance (which are then outspeeded by a DD Kingdra, unless it's a Scarfed Salamence or something (which I admit is quite common)), Kingdra is nearly impossible to kill if the rain is kept up. Keeping in mind what i said about other people having intelligence, even a Ninetails wouldn't switch in to Kingdra. For starters, outrage wouldn't be affected by the sun, and Ninetales, unless i've forggotten something, doesn't really have anything in it's arsenal to take down kingdra in one hit with. Not to mention, if the person with kingdra has brains, it would switch back into politoed, which again Ninetales has trouble dealing with. Tyranitar and Abomasnow don't really have much against a DD Kingdra with outrage either, even with a focus sash (and how often do you see those on one of them?).
Now, I know that some of you are probably tearing your hair off telling me that a Scarfed Salamence or Dragonite can easily take down Kingdra, I want you to keep in mind that DD isn't the only option with SS Kingdra (Swift Swim, not a ship). For starters, it works just as well with special attacking, and with a sash or, in a rare case, one of those resist SE berries, can ice beam any of those Dragons to death. Again, sash isn't something you see often on them.
What I'm trying to say here is, Kingdra is most likely to take out at least one of your pokemon or sweep your team whole if it sets itself up (if it needs to). It requires some pretty darn serious tactics to take it down. I understand that this probably doesn't hold water (see what i did there?) to move it to the uber tier, considering Reborn's fair system and the same sort of situation with ST Chandelure, but I would appreciate some feedback to this.
Edit: When Kingdra has a haban berry, a Scarfed Dragonite's outrage can't kill it in one hit. Just so you know.
Keep in mind that I'm not involving critical hits.
