Which coverage attacks should I use on this Slowbro set?

Question

I was thinking about using a Slowbro but I cant decide.

Nature: Modest
Ability: Regenerater
EVs: 252 S.attack, 200 def, 100 Hp, 58 S. def
Item: Leftovers
But it is the moveset that I cant decide

Calm-mind: Boosting
Psyshock/Ice Beam/Shadow Ball/Scald: I can't decide
Flamethrower: Coverage
Psyshock/Ice Beam/Shadow Ball/Scald: I can't decide

Answer 1

what about this?

Slowbro (M) @ Leftovers
Trait: Regenerator
EVs: 84 HP / 172 SAtk / 252 SDef
Bold Nature (+Def, -Atk)
- Flamethrower
- Calm Mind
- Slack Off
- Psyshock

if you use calm mind it helps to have a reliable recovery move to go with it.
psyshock is there to take down blissey and chansey,and flamethrower can be switched with scald if you want.
