RE: Tornadus, Thundurus and Landorus Pokemon Cards From Japan's Black Bolt + White Flare Sets
Shiny cards with arts tend to have higher price.
Cards that are good for competitive play have high value too.
Harder to find cards with cool arts have high prices too.
It is mostly demand that drives up the price.
