This set was removed from the analysis and I don't know why? I've been using this set to the extreme lately and it still works perfectly.

<p>Kingdra's Dragon and Water STAB form a nearly perfect combination to make an effective Choice Specs set. Dragon and Water hits everything in OU except Empoleon for neutral damage, so there is no reason to use any other attacks other than STAB for this set. The idea is to come in on predicted non-damaging support moves, or Fire and Water attacks and unleash pain on your opponent. Draco Meteor and Hydro Pump are good early game moves for tearing wholes in the opposing team. Dragon Pulse and Surf make good moves for cleaning up in the lategame, with decent power and perfect accuracy.</p>
<p>With four STAB moves, it is important to know when it is appropriate to use each attack. Both Dragon and Water as types have very strong neutral coverage hitting most types for consistent damage, therefore either STAB is usually a safe option. However, the choice on which move to use depends mainly on what Kingdra switches into. For example, if Kingdra switches in on a Heatran Fire Blast in the early game, Draco Meteor is the best option to use as it will beat Naive Scarftrans whether the switch or not, and will maim the incoming Water resist. If Kingdra switches into a Choice Latias locked into Surf, Hydro Pump becomes a better option to nail the incoming steels. In the mid to late game, Surf and Hydro Pump are generally safer options because most Water-resists are water-type Pokemon and do not threaten Kingdra directly.</p>
<p>While Draco Meteor is the most powerful move on the set but comes at the price of harshly lowering the special attack after each use. Therefore, it should be used prudently to prevent the opponent from setting up. Draco Meteor along with with Kingdra's decent Speed and bulk make this set a good revenge killer and psuedo counter to certain threats such as Gyarados and Will-O-Wisp or Overheat Rotom-A.</p>
<p>The EVs on the set allow Kingdra to outspeed Adamant Lucario, Jolly Mamoswine and Adamant Gyarados before a Dragon Dance, which gives Kingdra a chance to defeat them before they wreak havoc. It is important to note that the preferred ability on this set is Swift Swim, because a Timid Kingdra with 286 Speed outspeeds everything commonly seen on a Rain Dance team, and other Kingdra almost never run +Spe nature thanks to Dragon Dance and Rain Dance.</p>
<p>Like any offensive pokemon, Kingdra will appreciate residual damage to secure more KOs. However, Specs Kingdra is more of a supporter for the team, as it offers a very sturdy resist to Fire and Water attacks and the power to retailiate against many pokemon that carry those moves. Therefore, pairing Kingdra with Pokemon that have weaknesses to these types will allow more opportunties for Kingdra to get in and fire off attacks. One thing to note is that Kingdra is susceptible to Toxic Spikes and neutral to Stealth Rock, so a grounded poison-type or a rapid spinner will increase the amount of times Kingdra will enter the field to do damage.</p>
