Gotta admit I was playing Skellige. After I reach rank 18 I just kept losing with my NG. Tried out a couple if different decks in casual and quite enjoyed Skellige Discard. Helped me reach 4200. However in the end, 80% if not more was mirror matches.
Eventually figured that a lot of times losing first round was better than actually winning it. Assuming the frequent +-1 card layout. Due to carry over that often gave me a card up for last round.
Okay, now I kinda derailed. Sorry xD
