A handy secret in certain situations in when you opponent has a lot of weaker minions on the board with yours empty nearly depleted, if they attack your hero they may see their entire board being wiped in an instant. Keep in mind that this effect takes place AFTER your hero takes damage, so don't expect it to deter a heavy attacker even if it's almost dead. However if you play this card right before a situation like the former, it may come as a predictable move and your opponent may plan accordingly by buffing or healing their minions.
