The game runs fine on my device, sometimes I crash, whatever. I'm using a note 10. My wife's game crashes more. Her device is a bit older. Me and her are well aware that older devices crash more on games like hearthstone/codm these games require more power. However blizzards greed makes the game unplayable for new friends. Try explaining to your friends it will take them 2 years before they are caught up in standard, let alone wild. And stop adding new modes. I don't like auto chess I like tcg
