>>21337008Gravity+EP could be useful so if you want to break through Skarmory easier, and Magnet Rise gives it an EQ immunity which is wonderful. Heal Bell, Helping Hand, and Iron Defense might be only useful for non Mega. It can play a role as a backup cleric and it could use Helping Hand on Trick Room doubles teams. Trick Room is more viable in doubles than singles too. Iron Defense might be only useful on RestTalk if want a physical wall, but I doubt it would be good at that.
>>21339947Naive if you need speed and if your running Diamond Storm, Rash for extra power at the cost of speed, Timid if your going to run nothing but special attacks.
I think this might be the standard:
Diancie@Diancite
Naive
8Atk/248SpAtk/252 Speed
Diamond Storm
Moonblast
Earthpower/HP Fire
Calm Mind
For pure special:
Diancie@Diancite
Naive
4HP/252SpAtk/252 Speed
AncientPower/HP Fire
Moonblast
Earthpower
Calm Mind
The first 60 BP moves would hit decently after a boost. And if you manage to get the secondary effects Ancientpower offers....oh damn
