I do check out Hearthstone competitive news once in a while and a player that consistently do very well in tournaments is Kolento. (Twitch page, Wiki Page) He dominates them with very high win-rates and 0-1 losses in quite a few of them, which was very impressive. Here's the deck-lists to his 4 BlizzCon Europe decks:
Warlock Handlock
Shaman
Priest
Druid
