It seems a little bit like jumping the gun, considering the game hasn't even officially made it out of closed beta yet, but the world's first professional Hearthstone: Heroes of Warcraft player has been signed by that mecca of elite gaming: Razer. That player is Jeffrey "Trump" Shih, whose TwitchTV channel can be found under the moniker TrumpSC. According to the FAQ on his channel, he's been playing card games at a high level since 2000, and started with the Invasion block in Magic: The Gathering.
In Razer's official announcement of the partnership, they stress that Shih is well-known for keeping an informative and engaging Twitch stream, explaining his choices as he's making them and offering commentary on the match at hand. Shih will be working with Razer to offer competitions and giveaways on his live stream, and will be competing in the Innkeeper's Invitational at BlizzCon next month. Congratulations are in order for Mr. Shih; and his signing may very well help open the professional doors for other avid and skilled Hearthstone players.
