The only thing I would recomend is to get it through trade.

Oh and I meant get the Pokemon through trade.

You need not get another fossil to get shieldon again. Unless you want to pull some kind of two for one trade. But anyway you can get unlimited shieldons quickly by breeding. Take shieldon and a compatible mate (the hard part) to the daycare in solaceon town. Put them both in there and walk around for a bit, if you come back and the dude is facing right you have an egg. Careful though, the female Pokemon will determine the species of your egg. So if you have a female shieldon, put it in there with a compatible make and youll get shieldon eggs. If you want a more risk free technique put ditto and sheildon in at the same time, it will give you shieldon egg everytime.

Oh, Shieldons are kool, I can see why you want another one. I have like 10 of it's fossils. There are a couple of methods that you can use to achieve your goal of getting another Shieldon. One way you can get a shieldon, is by going underground for hours and hours, and hope that you find the fossil containing Shieldon. This can take quite a while, but I find them fairly often, so you might get lucky. Another way to get a Shieldon, is to breed it with a Pokemon like ditto, so it can have eggs. In order for this to happen though, the shieldon has to be a female, if the Ditto is a female, then it will not work. Or, you could trade someone that has a Shieldon, and they would be willing to trade them to you. Either one of these way work, and by doing one of them, you will have a Shieldon army in no time.

You can find another fossil
Or
Trade for one
Or
This is the one a recommend, put it in the daycare center with a ditto, wait for a egg then hatch it.

P.S. Could someone please rate my team "tricky14! 1st"
