I updated my post with info on the sword Pokemon.
Espurr is available on Pokemon X and Y and is quite common on route 6! I run into them all the time. I could go capture you one and trade it to you if you'd like? Just tell me the gender you want and nature and nickname if you wanna be specific and I'll get to it. ^^

Also if you want to get a female Amaura, SAVE BEFORE YOU RESURRECT THE FOSSIL!
Female Amauras are so hard to get oh my gosh it took forever for me to get mine. ;; I think it has like a 12.5% chance of being female? Not sure, but I do know it's very rare.
