My replies in bold, here are some other decks I think that will be good.
LostGar - This is obvious. It's owning in Japan with a 4 prize format, think of what it can do in a 6 prize format.
Dark Disruption Toolbox - The only real staple cards are Lookers, Weavile, and Rocket's Trickory. Besides that, you have a decently open list on what you can do with the deck. I'd say that Umbreon, Zoroark, Mandibuzz, and Houndoom are all good techs for this deck.
Reshiram/Emboar - Use promo Shuckle and lookers for draw, Emboar for energy excel and Reshiram for those big hits.
Gothruzzelle/something - I want this to work so much, though it's still missing something. Once it finds a good partner, this will be an amazing top tier deck.
