Final Move for Scarfed Gardevoir?

Question

I'm currently training a Gardevoir for competitive use in ORAS, and thanks to some advice on another question I have changed it from bulky Calm Mind to a Scarfed Sweeper. But since Calm Mind can't be used on Choiced Pokés, I need a fourth attack to replace it. This is its build thus far:

Gardevoir@ Choice Scarf

Trait: Synchronize
Nature: Modest
EVs: 252 Spe, 252 SpA, 4 SDef
- Psyshock
- Moonblast
- Thunderbolt
- Ice Beam/Focus Blast/Shadow Ball/Energy Ball

I'm not sure wether to run Ice Beam for a BoltBeam combo, Focus Miss for Steel-types, or Shadow Ball/Energy Ball for general coverage. Thunderbolt can also be exchanged for any of the aforementioned moves if that would be best.

EDIT: It has been brought to my attention that Gardevoir does not have access to Ice Beam in ORAS. Thanks SM979.

Trick is easily a superior option to shut down walls for the whole match. But since you insist on more coverage, Shadow Ball/Focus Blast are the superior coverage options. Shadow Ball shutting down the likes of Mega Metagross and opposing Psychic types. While Focus Blast covers Steels which you lack coverage for.

Oops, I completely overlooked Trick. Thanks!
