The first set is rather terrible, IMO. Having a non-STAB Sacred Sword as Aegislash's lone offensive attack is asking for trouble and it will end up being walled by its fellow Ghosts. This is the more effective Wide Guard support set:
-Shadow Ball
-Flash Cannon/Sacred Sword
-Wide Guard
-King's Shield
Nature: Quiet
EVs: 252 HP/100 SAtk/156 SDef
Item: Leftovers/Weakness Policy
Aegislash one of those Pokemon that relies on moving last. If it were to strike first (starting from its Shield Forme), it
will get hit very hard after it attacks because its Blade Forme is very frail. The above set has Shadow Ball as a primary STAB. The secondary attack is rather flexible here: Flash Cannon for secondary STAB or Sacred Sword with unresisted coverage with Shadow Ball. The above set is only usable in doubles, as Wide Guard is rather useless in singles.
Shield Forme Aegislash is too bulky for Focus Sash. Substitute is a more reliable attack over Sacred Sword to let Aegislash avoid status problems. Aegislash has enough time to set up a Substitute, as it forces switches very easily:
-Substitute
-Toxic
-King's Shield
-Shadow Ball/Flash Cannon
Nature: Modest
EVs: 252 HP/252 SAtk/4 SDef
Item: Leftovers
The final set is complete and utter Taunt bait. Aegislash is also way too slow to use Destiny Bond. Refer to the first set I posted for a Wide Guard support set.
