Certain cards are not ment to attack other cards. Same goes for some specific constellations regarding taunts. I think what you are describing/wonder about, is how the bot actually handles logic as of right now.
Enemy had any taunts up? There is something weird with attacking taunts logic - bot sometimes do not attack at all just because there is a taunt.
