If you're going for a special Aegislash (As of the moves you have picked) I would go with this one:
Aegislash @ Leftovers/Weakness Policy
Ability: Stance Change
Level: 50
EVs: 252 HP / 4 Def / 176 SpA / 76 SpD
Quiet Nature
IVs: 0 Spe
- King’s Shield
- Shadow Ball
- Flash Cannon
- Wide Guard
Wide guard support, counter against Trick room pokemons, Survives a Flare blitz from a -1 Adamant choice band Talonflame and it can attack pretty well against the top 6 biggest treats once his Weakness Policy is activated: http://i.gyazo.com/8f277418e586926da31aee8897d1a20e.png
