The explanations are a bit lacking, but they all have good movesets and their types are good(except for 3 dragons, which might not be a bad thing) Bravo.
Arceus + Icicle plate = fail.
Revise your team-buidling skill a bit more.
Deoxys never wins a battle, no joke.
Your Darkrai's rubbish. The right move set should be:
Dark Void
Dream Eater
Nigfhtmare
A decent offensive move
Way too many dragons.
Hyperbeam = fail.
Outrage always backfires.
TOO MANY UBERS!
Why am I even bothering?
If you wanted the ultimate team, you could exchange 2 dragon types with others. Types are essential. Your team is still powerful, but why is your Darkrai holding a Masterball?
well this is ok, so i'll give it a 3. Try this Darkrai Set it works very well :)
Darkrai @ Focus Sash
Timid(+Speed - Atk)
Ev: 4 Hp 252 Sp.Atk 252 Speed
Dark Void
Nasty Plot
Dark Pulse
Focus Sash
-With Bad Dreams and Dark Void this thing gets annoying. While foe is sleepin take the time to x2 your Sp.Atk with Nasty Plot then Slap em with Dark Pulse or Focus Blast and with Focus Sash you'll make it through the first turn.
Hope this helped.
Deoxys doesnt need recover unless its defence form because it is way too frail to even take one hit, Fly should generaly not be on any moveset ever and hyper beam is just asking for a revenge kill
