How about some advice then? I just got my 7 day login bonus, but I can't get past league 20. Always seem to end up fighting the same person, who I can only guess is an ai since they have the same name as the tutorial pvp player, or someone imitating an ai. I only guess it's an ai because I found it strange to be matched against the exact same person 3 times in a row. I simply can't take down their 16 health high naga in 1 turn if they deploy it first, and if I take longer than 1 turn to kill it I more or less lost the match already.
Also keep getting matched against players with 2 month badges and usually can't win against them because they seem to have max level, and rebirthed cards or legendaries which I have none of. Even fought one today who started with a legendary 1st turn, then another legendary 2nd turn. I resigned since the match was already lost because I couldn't kill the first legendary in 1 hit.
