Dude do you want to kill that thing(staraptor) or what??
Brave Bird + ReckLess + Life orb = Death of a bird .
Remove the life orb and your staraptor is Complete .
Ability :Reckless
Close Combat (Eliminate Ice and Rock disadvantage )
Brave Bird (STAB,Reckless)
Double-Edge (STAB , Reckless)
Steel Wing / U-turn (Variety) - Go for U-turn .
Almost the same moveset but what can I do you are awesome at analysing advantages and weaknesses of a pokemon .
**I go with staraptor because archeops' ability ruins things easily and staraptor has a more than reliable speed and Attack .
Just remove life orb else it will become too risky .
And an amazing moveset to kill any ONE opponent ; try this ,
Endeavour
Endure (TM 58- Platinum/Hg/Ss)
Quick Attack
Agility
Agility set up speed if you are not dying in a OHKO .
Endure to take the hit and use endeavour when on one hp .
Use quick attack to wrap things up .
But this moveset is too unreliable so go with the one mentioned before .
