[ORAS VGC] Need Your Kind Assistance Please

[Tridentbolt]

I am looking to build a VGC team that I can use for Battlespot Ranking Double Battle. I know four Pokemons that I want for sure, but I am stumbling to decide which other Pokemons I can add to the team. Hope you guys can help me. Thanks!

My Team:
Clefairy (F) @ Eviolite

EVs: 124 HP / 220 Def / 4 SpA / 156 SpD / 4 Spe
Bold Nature

- Follow Me
- Protect
- Helping Hand

Aegislash (M) @ Weakness Policy
Ability: Stance Change
EVs: 252 HP / 12 Def / 164 SpA / 76 SpD / 4 Spe
Modest Nature
IVs: 0 Atk
- Shadow Ball

Salamence-Mega (M) @ Salamencite

Milotic (F) @ Rocky Helmet
Ability: Competitive
EVs: 228 HP / 204 Def / 68 SpA / 4 SpD / 4 Spe
Modest Nature
IVs: 0 Atk

My Suggestions:

I think most of the EVs I used was to survive common threats such as Landorus-T and Mega Kangaskhan. As I've stated above, I do not know who else to add in this team. Any and all suggestions and opinions are welcome. Thanks again!
