I have a couple of shiny Magneton and a shiny Magnezone if you are interested. They were caught by me on my Platinum version using the Poke Radar (and have been Poke Transferred to my White version). They are not RNG'd and have never been cloned. They are legit per your stipulations. I'd be interested in any of your shinies, but particularly the Tepig or the Druddigon.
Edit: To make this more clear, I'm offering 1 Magneton or Magnezone for 1 of your shinies.
I will give you the data on all three.
