[2020] To those who still don't know, you can get to 90 using AI matches so don't get yourselves in a knot like last time with the challenger quest and the mountain of posts about it. Have fun now :)

If you enjoy this patch's lab, it's pretty good for completing Teachings of the Dragon. You have plenty of turns where you are playing two spells and a lot of created cards, while earning petals for your wins.
