Nice article. I would like to add that if you have a friend who can watch you play and tell his opinions on different situations helps. When other person watches your game, he can give you other perspective on things. Me and my friend do this often and it helps both of us to avoid misplays and get better with decks. I reached legend in april season for the second time, this time with miracle rogue (winrate 57% from rank 5 to legend).

Two minds often work better than one.
