How do I breed a Ghost Dragon in DragonVale?

Looking for the fastest breeding combo to breed a Ghost Dragon? It so happens, we here at WOTS have just that. Read on below. The Ghost Dragon was brought back as part of the "Bring 'Em Back" event, but that's now over. Hopefully that doesn't dampen your spirits too much :) .

Breeding Time: 15 hours and 30 min or 12 hours 24 min (with upgrade)

This dragon, like the Bone Dragon is pretty cheap to buy. Consider it, if you are running into trouble breeding.
