Overview

Deoxys-A is generally the better pick between the two Deoxys since its Attack and Special Attack stats are far superior to that of this Deoxys.

Name Item Nature

Special Sweeper

 Petaya Berry Mild
Moveset EVs
~ Superpower / Calm Mind
~ Thunderbolt / Thunder
~ Ice Beam
~ Substitute
4 Atk / 252 SpA / 252 Spe

You'll probably want your HP to be divisible by 4, in case of Tyranitar, so you can activate your Petaya at 1/4 instead of 1 HP. Unlike Deoxys-A, Calm Mind is a lot less of an option, because Deoxys doesn't force switches as well, thanks to its lower Attack.

Name Item Nature

Choice Band

 Choice Band Lonely
Moveset EVs
~ Superpower
~ Shadow Ball
~ Fire Punch / Thunder / Ice Beam
~ ExtremeSpeed
252 Atk / 4 SpA / 252 Spe

A Choice Band Deoxys. Basically this fails in every regard compared to Deoxys-A, but if you want to still use this Deoxys forme this can work, but to a lesser degree.

Other Options

There is virtually nothing else viable. Psycho Boost can be used, but it won't really hit anything harder than your other moves.

EVs

360 Speed minimum, generally max. Max out Special Attack +nature, for the first set, Attack for the second. Don't even bother with defenses. This is from Deoxys-A, but basically it stands correct.

Checks and Counters

Just attack away at this thing. It has better Defensive stats than Deoxys-A, but just like Deoxys-A, it can be taken down easily.
