I've had more than one face-palming game. I've done a lot of the things mentioned already. Scorched my own units, passed when I shouldn't have, miscalculated math due to ongoing effects like weather, etc. But the thing I do occasionally that really bothers me the most is when I play a card that searches for another card forgetting that I've already used the card I'm searching for. For example, the gold skellige card that searches for a unit to fling at your opponent and only finding a 1 power revive a unit card =/
