The Hearthstone World Championship is currently going on and there are lots of exciting matches. Here's the schedule and players from Blizzard's official site. Matches can be viewed live from Twitch (the broadcast page also has tournament broadcast schedule below the video player) or Youtube. The VODs (Video-On Demand) of matches are also available from those sites.
One match I watched was Firebat vs Qiruo and Firebat used an interesting Miracle Rogue deck. It uses Southsea Deckhand + Cold Blood + Faceless Manipulator combo as a finisher and able to go 3-0 in the series. There was a Reddit discussion on the deck and many were saying it is not something new. Here's the deck-list by karapiper from HeathPwn.
