I don’t know what decks are popular to use nowadays but as far as I know, it’s still Murloc Shaman. (Because of the new card) Although in the first day of WCG’s Grand Finals for Hearthstone category, they often use warrior decks or mage decks.

I hope this one will update soon, especially with the new build and the new set of cards. By the way, my favorite hero would be the Priest but when it comes to daily rank match, I use my rogue.

This has been very helpful along with some matches of WCG and HS Grandmasters and gameplay of
Thijs Hearthstone, I would watch them and incorporate what I have learned from here. Glad to say, I’m in rank 10 in my server.
