Shadow Madness (or even potion of madness) don't work properly. The first one it says "that's not a valid target", even if the selected minions has 3 or less attack (it allowed me to steal a totem tho, for some reason). Potion of madness is even more messed up, I played the 1/1 with two 2 atk minions on opponent's board and nothing happened, as if there weren't options for the spell to be casted and skipped it straight away

I understand your frustration.
Didn't do anything with Shadow Madness for me, didn't even try to target anything just like how you described Potion of Madness.
Well, they are a small indie company after all -.-"
