I found this very helpful. I'm TERRIBLE at Hearthstone.Building decks for use in Play mode can be a very satisfying process. From coming up with your unique deck concept to playtesting it and tweaking it to perfection, constructed play is a great way to test your overall skill and knowledge of the game. Many of our Hearthstone fansites have contributed their insights on deckbuilding to this blog, to help you along the way to building a deck of your own that’s fun to play for the class of your choice. The links and summaries below are all to be taken as helpful guides, not the end-all be-all of Hearthstone deck creation. So take some time to read the guides, pick out a few new ideas that appeal to you, and then dive in to building a deck of your very own!
Seriously.... beyond terrible.
