toast has a pretty good new players guide with decent free decks you can make:
there are a just couple of things i tell new players to focus on:
-don’t rush your turn and play your cards out because they’re green. think your turn through and then play your cards.
-always be counting for lethal damage. even veteran players can tunnel vision on board control and lose a game. as i get towards the later turns of the game i keep a running total of the damage i can do.
-don’t get mad or discouraged when you lose. think about things you could have done better. like all card games hearthstone is about building up a huge library of experiences that inform your decision making in the future. if your opponent does something good and beats you they just taught you a valuable lesson about how to win in the future.
-watch a lot of streamers play the game. because it’s a card game you can actually learn a lot by watching other people play. i suggest clicking around on the top few streamers and finding someone you like.
