I ' m gonna go ahead and say that skill matters more than you think . One of the key reasons why people think HS is super RNG is because many games end with an RNG outcome , e . g . a topdeck . I have seen this so many times in Hearthstone as well as Magic . However , many many many of the unlucky situations could still have resulted in a win if the player had performed better in the early turns . The most classic example of this is dying to an exactly lethal topdecked fireball when your opponent is dead on board . If you took one extra damage due to bad sequencing or similar very common , that loss would have been a win . After that game , are you more likely to blame your misplay or the opponents luck ? I dont know your skill level , but for weaker players , the answer is usually blaming luck . In fact , many will continue to blame luck even after you challenge them , asking well why did you make that play on turn 3 ? and so on .
