I NEED HELP!!!!

I want to get all the Pokémon from my stories on to my aS game. I already got a Vulpix named Ruby, and a Espurr named Flash, and many more Pokémon, but...

I can't get a shiny Eevee for Shimmer!

Does anyone know where I could get one? Or how to? I tried DexNav but I'm just plain AWFUL at it...

Help? Please?

I have a Phione you could have! ^-^

Please?

Pretty please?

Please with a cherry on top?
