<p>Offensive Deoxys-S is often cast aside by many uber players in favor of its much more powerful form, Deoxys-A. While it is true that Deoxys-S won't even come close to hitting as hard as Deoxys-A, its 30 point higher base Speed can make Deoxys-S a more effective revenge killer in a tier where almost nothing outruns it, including many Choice Scarf Pokemon that sit at Speeds lower than 500. Its incredible Speed makes it a great revenge killer and with its impeccable coverage can take out a surprisingly wide variety of threats in the uber tier.</p>
<p>With a Naive nature and 236 Speed EVs Deoxys-S is able to outrun Jolly Choice Scarf Garchomp and anything slower. 100 Attack EVs allow Deoxys-S to OHKO Darkrai, on average; and always with Stealth Rock damage, with Superpower. They also allow Deoxys-S to 2HKO uber Blissey (Calm, 4 HP / 252 Def) and 120 HP EV Mild Dialga. The remaining EVs were distributed to Special Attack and give Deoxys-S the ability to function as a revenge killer to some dangerous threats in the uber metagame. Deoxys-S is capable of outrunning once Dragon Danced Rayquaza and Choice Scarf Garchomp, and OHKO with Ice Beam. An interesting note is that Jolly Rayquaza only has a 7.69% chance to OHKO Deoxys-S with Extremespeed, making Deoxys-S a decent check against even those Rayquaza with Extremespeed. Additionally, Deoxys-S is able to 2HKO almost all Groudon with the same Ice Beam. Thunder is for Lugia and Kyogre, both of whom are 2HKO'd with Stealth Rock damage. Thunder also can be used to pick off weakened Palkia. Finally, Shadow Ball is mostly for Mewtwo and Deoxys-A who are 2HKO'd and OHKO'd, respectively, with again the help of Stealth Rock.</p>
