Good morning.
I would like to report a bug.
It is impossible to finish Secret Laboratory board clear (Clear Dr. Boom, 4/4 fight). Why? Because two cards Sorcerer’s Apprentice don’t reduce mana cost of our spells enough. Some of our spells should cost 0 mana (like Defile or Demonfire), but they cost 1 mana.
Best regards, Rafał
