There also appears to be an error with the list for Master player Calvin Nordberg. The website shows 63 cards including 5 Thundurus EXs
Additionally, the Flygon list on the "popular decks page" (http://www.pokemon.com/us/play-pokemon/nationals/2014/decks/popular/) seems to be missing Dusclops/Dusknoir, but features extraneous Munna and Scraggy.
Brandon Salazar's Landorus/Mewtwo/Raichu/Garbodor says 7 Darkness energy instead of Fighting. You might want to look over all of the posted decks just in case.
