Calm Nature (+SDef, -Atk)
- Surf
- Rest
- Ice Beam / Grass Knot
- Toxic
I ran this guy in my rain team to handle Darkrai (especially lead Darkrai). It can handle +2 Dark Pulses easily and hit back with Surfs that 2HKO. Ice Beam works to kill Lati@s without Thunder as well as Garchomp and unboosted Rayquaza that won't usually OHKO, but Grass Knot is the best option for hitting Groudon and Kyogre. Toxic can be replaced by some other stuff, but it's usually the best option to kill guys like Lugia and Specially Defensive Giratina, plus it eventually forces Blissey switches and is the best option to wear down Calm Mind boosters and Deoxys-D. If toxic doesn't fit your team, then I've found Reflect, Tail Glow, or Knock Off are pretty cool choices.
If only Manaphy could get Thunder Wave =[
