This belongs in GB Strategies & Movesets, but I will respond while a mod moves it there. To be honest, that is not a good moveset. At all. Using a Choice Band on a Poke that only has one physical move isn't good strategy. The moveset isn't helping either. Hyper Beam is the absolute worst move you can have on Deoxys-FR. All your opponent has to do is switch in a Gengar, making it miss, and then it has a free shot to murder your Deoxys since you cannot switch out on the second turn while it has to recharge. Zap Cannon is also a very bad idea. At 50% accuracy, if you miss your Deoxys is dead. It is also a special move, so you won't get any CB boost from it at all. Speaking of special moves, having two Psychic-type moves is redundant and really limits its ability to hit different types.
If you want a CB Deoxys-FR, this would be much more effective:
Deoxys-F @ Choice Band
EVs: 252 Atk / 252 Spd / 6 SAtk
Hasty Nature (+Spd, -Def)
- Extremespeed
- Psycho Boost
- Shadow Ball
- Superpower
Extremespeed is a go first move (which you need with such a defensively frail Poke) that does more damage attacking twice in two turns than Hyper Beam can attacking once in two turns. Plus you aren't leaving it hanging out to dry. Psycho Boost is self-explanatory. Shadow Ball can destroy other Psychics and especially Ghosts that might resist your other attacks. Superpower takes out Darks and with the CB boost, your 1 stage Atk drop isn't that bad and who cares about Def?
