Walking around with a Pokemon with Pickup. (Four percent chance at levels 41-60, 10% chance at levels 61-100.)
Secret Super Training (Drag Down Hydreigon)

Both of these would map over to Y. Unsure if Inverse Battles would as well, I only ever did it once so I don't remember his prize structure in X/Y. Pick-up is very effective.

I'm a fan of the super secret training. Definitely the fastest way to get evolution stones of any kind.

Answer 2

You can thief/covet moonstones off of Lunatone and Clefairy, and at a certain level have a chance of Pick-up handing you one, if Super training isn't coughing one up.
