Team is pretty nice, but a phazer can really mess it up because most of the pokemon are set-ups, and I see no bulk except for the natural bulk in Conkeldurr so hazards can eat through your pokemon making an easy kill for your foe.
As for threats in pokemon, Sableye can do some damage with it's swagger/sub/will-o-wisp set. There is no major weaknesses.
Raikou doesn't really need Shadow Ball, and Weather Ball in Rain gives Ground coverage so try this?
Raikou @ Life Orb

Timid Nature (+Spd, -Atk)

You can replace Thunder with Thunderbolt if you want, just put it in there assuming rain was still up.
