Durant finds its niche in OU as a high risk, high reward Pokemon. Thanks to Hustle, Durant's Attack is higher than any other Pokemon in OU and with its good coverage, Durant is almost impossible to wall. In addition, it sports a base Speed stat of 109, making it faster than most of the tier and allowing it to just barely outpace Pokemon such as Terrakion, Keldeo, and Infernape. Finally, Hone Claws allows Durant to get past even the sturdiest physical walls in OU, such as Hippowdon and Skarmory, and fixes the lowered accuracy caused by Hustle.
Although Durant looks extremely difficult to stop, it has a number of flaws. Its Special Defense is downright awful, and it will almost never take a neutral special hit. While its Speed is good for outpacing some Pokemon, it finds itself barely outsped by many special attackers, including Latios, Gengar, and Starmie. Also, while Hustle is Durant's big selling point, the accuracy drop that comes with it can be fatal. It has Hone Claws to fix this, but this is difficult to set up with Durant's bad special bulk. Overall, Durant is a high-risk, high-reward Pokemon, and must be considered as such when being placed onto a team.
If Durant has any hope of competing in the OU environment, this is arguably the best set it can have. Thanks to Hustle, it hits very hard, even compared to the titans of OU, and its Speed allows it to outpace common Pokemon such as Terrakion and Keldeo, allowing it to be a formidable offensive threat. Iron Head is the main STAB option, OHKOes most offensive Pokemon that don't resist it after Stealth Rock, such as Dragonite and Terrakion, and hits even Pokemon that resist it for considerable damage. Superpower was BW2's gift to Durant—it is Durant's best option against the omnipresent Steel-types in OU, and OHKOes Pokemon that previously could defeat Durant such as Heatran. Despite Thunder Fang's low Base Power, it hits Keldeo, Tentacruel, Skarmory, Jellicent, and Gyarados for massive damage, all Pokemon that otherwise counter Durant.
The last slot comes down to personal preference, as well as confidence. As mentioned in the overview, Hone Claws is difficult to set up, but it complements Hustle well. After one boost, it fixes Durant's accuracy problems while allowing it to power through some of its usual checks—Thundurus-T, for example, is OHKOed by Iron Head at +1 after Stealth Rock damage despite it resisting the move, Hippowdon is 2HKOed by Iron Head, and Skarmory is 2HKOed by Thunder Fang. However, Durant finds it hard to set this move up due to the prevalence of Choice Scarf users and faster special attackers that can threaten to destroy it easily due to Durant's bad special bulk. If this is a problem, X-Scissor is another STAB option. While it doesn't gain that much additional coverage, it allows Durant to OHKO Celebi, Latias, and offensive Reuniclus, OHKOes 252 HP Jirachi at +1 after Stealth Rock and one layer of Spikes without cutting Durant's sweep short like Superpower does, and hits certain Pokemon for the same damage as Superpower but without lowering Durant's stats such as Rotom-W, Gastrodon, and Metagross.Team Options & Additional Comments >>>
Durant has a shallow movepool, but it has a few other options. Choice Band can be used instead of Life Orb to make Durant even more powerful, but Durant's real strength lies in its ability to switch moves and possibly boost with Hone Claws. Agility or Rock Polish are decent options, as Durant isn't weak to any priority moves and the opponent will have a tough time outspeeding it at +2. However, Scizor's access to Bullet Punch and Swords Dance makes Scizor superior in most cases. Thunder Wave is always a useful support option, but Durant is much better suited to being on the offensive rather than spreading paralysis. Baton Pass can be used to pass off a boost at the last minute, but Durant will rarely even have the opportunity to use Hone Claws in the first place. Substitute is useful mainly because it is the only way Durant is going to take a special hit from a Pokemon such as Starmie. As a side note, do not use Wide Lens—even though it somewhat improves Durant's accuracy, it doesn't offer any additional power, which is Durant's main (and really only) advantage.
Checks and Counters
Due to the immediate power it brings onto the field, Durant can be tricky to stop. Forretress is the only true counter to Durant in OU, as it can avoid the 2HKO from everything Durant has and use Volt Switch to bring in a faster Pokemon that can KO Durant. Without Rock Slide, defensive Zapdos counters Durant as it avoids a 2HKO from all of Durant's moves even at +1. Physically defensive Hippowdon and Skarmory avoid the 2HKO from unboosted Durant and can either stall it with Life Orb damage or phaze it if it attempts to set up, acting as good checks. Landorus-T avoids the 2HKO from anything that Durant has and deals 60% damage minimum back, meaning that it is a good check after Durant suffers a couple Life Orb rounds. Choice Scarf Magnezone or Magneton can switch into any of Durant's moves other than Superpower and trap and OHKO it with Thunderbolt. Jellicent, Tentacruel, and most other bulky Water-types can switch into an Iron Head, survive one Thunder Fang, and hit hard with Scald, potentially burning or outright OHKOing Durant. However, a much safer way to defeat Durant is by revenge killing it. To put it bluntly, any Pokemon either holding a Choice Scarf or that has a base Speed over 109 with a neutral special attack is going to either force Durant out or destroy it. Examples of these Pokemon include Choice Scarf Keldeo, Starmie, and Gengar, and if Durant has Hone Claws, these Pokemon will discourage its setup heavily. Be warned that some of these Pokemon, such as Alakazam and Gengar, must sometimes rely on the inaccurate Focus Blast, while Durant can OHKO most of them in return.
