When I get one of those free Arena tickets I just go in blindly pick whatever then retire before playing a single game…
Arena is a joke so I find it easier and less stressful to do it that way.
It’s a game bro. If playing hearthstone is that stressful, you could just…turn it off.
What I like to do: I play until I have 2 losses. Then I sit on it until the season ends. I get the ticket back and repeat the process. I can get to 10 wins, sit on it, claim the rewards at the end of the season and get the ticket, too. I don’t play arena bc it’s pay based, but it’s worth it for the free stuff.
