Well, It doesn't learn recover, so might update the OP.
Anyways, that wonderful base 107 Special Attack could run a Calm Mind set...
Item: Leftovers
Nature: Modest
Evs: 252 HP/ 244 Def/12 Special Attack
Calm Mind
Energy Ball/Shadow Ball
Psycho Shock/Charge Beam
Moonlight
Since Musharna Doesn't have the best Defense, you could probably use some investment in there since its Special Attack doesn't need much investment. (NOTE: This would be for OU, since it has great defenses otherwise. However, with Sazandora and the like running around, It might be needed to put some in Special Defense at the cost of HP evs.)
