Not sure if any of you play hearthstone but I was playing this morning trying to complete a quest.  I had my opponent at 3 life and I was at 18 life.  He had 4 creatures and started casting spells buffing them up to which gave him enough damage to kill me.  He then casts 2 spells to give himself attack power and uses his hero power to give himself another point of attack.  When he used his hero power it triggered a secret I had cast early in the game that does 5 damage to a random enemy.  The random enemy it chose was himself.  So by showing off and trying to overkill me he killed himself.  I laughed like crazy when that happened.
