Although its stats might indicate otherwise, Deoxys-D is the premier offensive lead Spiker in the OU metagame. Its base 90 Speed stat allows it to outpace just what it needs to, while its enormous bulk makes it nearly impossible to take down in one blow, allowing the user to get at least one, if not two, layers of entry hazards up. This consistency appeals to many players, and as the generation has progressed, so has Deoxys-D's recognition as one of the best. Not only does it have the tools necessary to be a great Spiker, but it can also run certain moves to ensure that its work cannot be blown away by common Rapid Spin users. It has essentially defined the new, fast-paced BW2 metagame, as it is used on nearly every hyper offensive (specifically weatherless offensive) team. Unfortunately for Deoxys-D, it is a Psychic-type, which leaves it vulnerable to many common attackers, most notably Scizor and Tyranitar. It also has no way of breaking through either of the Magic Bounce users, Espeon and Xatu, rendering it essentially useless as long as those Pokemon are in battle. Despite these flaws, Deoxys-D has risen up to the cream of the crop, firmly holding a position as one of the elite Pokemon in OU.
Deoxys-D's solid Speed and bulk make it a fantastic fast Spiker. This set is especially effective at being a suicide lead because of its ability to set up multiple layers of entry hazards. The primary purpose of this set is to set up as many entry hazards as possible while preventing opponents from setting up their own entry hazards. As such, you shouldn't play with this set conservatively, especially if you see that your opponent doesn't have a spinner or Magic Bounce user. With its high bulk, opponents will be hard-pressed to prevent Deoxys-D from getting two layers of entry hazards up. Its above-average Speed allows it to prevent Pokemon such as Hippodown and Skarmory from setting up entry hazards of their own with the use of Taunt. It also has the benefit of guaranteeing that Deoxys-D won't be setup bait for Pokemon such as Dragon Dance Dragonite and Gyarados.
The last moveslot depends on what you want Deoxys-D to beat. Magic Coat can be used as with proper prediction, it can cause major headaches for your opponent. It allows Deoxys-D to reflect Taunts aimed at it so that it can set up entry hazards undeterred. It is also incredibly convenient if you are facing an opposing Deoxys-D, as it will bounce back Taunt and render your opponent's Deoxys-D useless. On the other hand, with Night Shade, it is a solid counter to Calm Mind Reuniclus. It is able to Taunt Reuniclus to prevent it from using Calm Mind and Recover, then dispatching it with Night Shade. Do be warned that if Reuniclus has Shadow Ball, Deoxys-D will always lose. Night Shade also has the added benefit of preventing faster Pokemon such as Gengar and Terrakion from setting up a Substitute on you.Team Options & Additional Comments >>>
This set takes a different stance on the suicide lead aspect. One of the biggest problems with the speedy Spiker is that it is extremely vulnerable to having its entry hazards spun away by the likes of Forretress and Starmie. This set alleviates these problems. Hidden Power Fire destroys Forretress, ensuring that it will not get away with spinning away your hard work. It also has the added benefit of roasting Scizor, a common switch-in to Deoxys-D. Although Thunder seems like an odd option over Hidden Power Fire, it allows Deoxys-D to OHKO Starmie, letting you set up entry hazards in peace. Now, while the offensive Spiker is effective at removing certain threats, one must not forget what its main purpose is: to set up entry hazards. This set maintains plenty of Speed and is able to set up entry hazards on slower threats with ease.
A Modest nature along with Special Attack investment is required to let Deoxys-D damage as much as possible. Unfortunately, full Special Attack and Speed investment means that Deoxys-D isn't as good at taking hits as one might think. Psycho Boost is its strongest STAB and with a Life Orb boost is actually quite strong. It lets Deoxys-D OHKO Tentacruel, which prevents it from using spinning away your hazards. It is a generally strong move, being able to OHKO offensive Pokemon like Haxorus. The move you decide to use in the last slot is heavily dependent on your team. If your team prefers Starmie being eliminated, you should choose Thunder over Hidden Power Fire. Hidden Power Fire is useful for crippling Steel-types that may cause your teammates struggles.Team Options & Additional Comments >>>
Deoxys-D can make good use of its high bulk and Speed to run an efficient dual screens set. While one might think that a faster Pokemon such as Azelf would be a better option to set up a hyper offensive attack, Deoxys-D fares just as well;—sometimes even better. With its base 90 Speed, it is able to outrun a good amount of Pokemon, and consequently set up screens before they can attack. Its high bulk is useful as even if it faces a strong attack, it's more than likely still able to set up a screen. This set separates itself from dual screen Espeon as even though it is unable to reflect hazards, Deoxys-D is able to use its bulk to set up screens at multiple points in a game, something Espeon struggles to accomplish. Deoxys-D can also prevent entry hazards from being set up on it by slower Pokemon through the use of Taunt.
The moveset and item are fairly self-explanatory for this set. Reflect and Light Screen allow Deoxys-D to support its teammates phenomenally. Light Clay is crucial for its ability to extend the duration of Reflect and Light Screen for 3 more turns. Taunt is useful for its ability to prevent slower Pokemon from setting up on Deoxys-D, an incredible asset considering its above-average Speed. Stealth Rock allows Deoxys-D to further expand on its supporting ability by helping its teammates finish off opponents that would usually avoid the KO with the lack of Stealth Rock. An EV spread with maximum HP and Speed is most efficient as it allows Deoxys-D to maintain a good amount of bulk, while making the most of its Speed.Team Options & Additional Comments >>>
While many of Deoxys-D's other sets take an offensive approach on the battlefield, this set is the opposite. Instead, this set aims to utilize its amazing bulk in order to set up as many layers of Spikes as possible over the duration of the game. With a fully invested Special Defense stat, Deoxys-D becomes a behemoth to take down. Even a Choice Specs Latios Draco Meteor will fail to 2HKO it, suddenly transforming Deoxys-D into an enormous help to stall teams that do not want to risk an unexpected Psyshock to their Blissey or Chansey. Deoxys-D also serves the essential role of Calm Mind Reuniclus counter for stall teams—with the combination of Taunt and Night Shade, Reuniclus has no chance of beating it. With its ability to wall the vast majority of special attackers in the tier, Deoxys-D has plenty of opportunities to set up Spikes and wreak havoc.Team Options & Additional Comments >>>
Despite Deoxys-D's wide movepool, in all actuality it has very limited options. You can forgo even thinking about an offensive set as despite its rather excellent coverage, Deoxys-D won't be nearly as powerful as even Pokemon like Pachirisu. A Red Card + Recycle Spikes set is nifty in the sense that it racks up residual damage rather quickly. Calm Mind and Cosmic Power fall into the same boat of Deoxys-D being too vulnerable to common status conditions such as Toxic poisoning. Likewise, Deoxys-D can utilize a set featuring Agility / Toxic / Recover / Taunt in order to stall out a good portion of the metagame; however, it is left vulnerable to literally every Poison- and Steel-type. Ice Beam can be used if you dislike the sight of the plethora of Dragon-types that will attempt to set up on you and are too fast for Taunt, such as Garchomp and Salamence. Another option is to run a basic walling set, with Taunt, Toxic, Recover, and Night Shade, although this is outclassed by some more conventional walls that have better typing, such as Skarmory, or better defenses, such as Blissey.
Checks and Counters
For a Pokemon to be classified as a "counter" to Deoxys-D, it must be able to prevent any layers of entry hazards from being set up. Deoxys-D's main job is to ensure that entry hazards are set up on the field, so combine its high bulk with its good Speed, and it is very hard to stop it from doing its job. However, there are a few Pokemon that completely shut down Deoxys-D from getting even one layer of hazards up. Xatu and Espeon can be classified as counters, as Deoxys-D will actually hurt its own team if it decides to set up hazards, due to Magic Bounce. Once in play, there is little to nothing that Deoxys-D can do to affect Xatu or Espeon in any productive way.
Deoxys-D's list of checks is much bigger than its list of counters, and a check to Deoxys-D qualifies as limiting it to one layer of hazards. Choice Band Tyranitar is the prime example of this, achieving the OHKO with its STAB Crunch. However, one should be wary of using it as their main Deoxys-D check, as Deoxys-D is commonly paired with Pokemon such as Terrakion and Lucario, both of which have access to Justified, making Tyranitar an extreme case of being a set-up fodder. A combination of Scizor and a faster Pokemon can limit Deoxys-D to one layer of hazards, as Scizor's U-turn will put big enough of a dent into Deoxys-D for it to be picked off by most fast attackers. Gengar fears the occasional Thunder Wave, but besides that, has no problem with 2HKOing Deoxys-D with Shadow Ball, limiting it to only one layer of hazards. Volcarona is very much in the same boat as Gengar, although it has the added advantage of being able to set up on Deoxys-D with Quiver Dance, a fate few wish to go up against. Honestly, anything that can set up boosts on Deoxys-D can be classified as a check to it, as few trainers will allow their opponent to set up multiple boosts on such a susceptible Pokemon like Deoxys-D. Rock Polish Landorus and Nasty Plot Thundurus-T come to mind, as both are immune to the occasional Thunder Wave, meaning neither have any fear when it comes to setting up on Deoxys-D.
A fast Taunt is the enemy of all Deoxys-D lacking either Magic Coat or Mental Herb, as it disables Deoxys-D from achieving its main objective. However, using Taunt against Deoxys-D is a very risky move, as more often than not, it will be equipped with either one of the previously mentioned tools, relegating your Pokemon into an unfortunate state. Regardless, if you are a player that plays with their balls-to-the-wall and want to attempt this strategy, Prankster Pokemon, such as Tornadus and Sableye, are an effective way of doing it. Finally, a well-timed Rapid Spin can essentially be considered a counter, as it removes the work Deoxys-D might have done. However, Deoxys-D will often be paired with a Ghost-type, making Rapid Spin very hard to use.
