I want to breed a Furfrou for wifi battles. I know it's not fantastic but it's a lot better than I expected and it's one of my gen favorites, so I want to make it as viable as I can. I don't know a whole lot though and I would like some advice.

Base stats are 75/80/60/65/90/102.

I think going with a -SpAtk nature is pretty obvious, but what should I choose for the increased stat? Atk, Def, Spd, or SpDef? Obviously defense is its main thing, but it could use some attack power and speed for when it's not walling. I also don't know if its special defense needs a buff or not.

For IVs, SpAtk doesn't look like it matters much, but it looks like I'll need 31s in at least all the defensive stats? Maybe speed and attack too?

For moves all I've really thought of are:
Return
Cotton Guard

And I'm not sure what sort of item.

tl;dr I'm a competitive babby and I need help with basic shit
