its fun to play. and near to impossible to loose against any ai3.
but there are some posibillities to not get a em with this deck.
you gain health with attack, that means:
if attack (from vamps/dagger) < hp you need for 100hp -> no em
also you have to watch the order you play your creatures to gain ems:
pest<dagger<vamps<dusk mantle<gargoyles -- eclypse=situational
you can wait some turns untill you draw more vamps, instead of playing a gargoyle (witch can cost you a em). but i was mostly not that patient^^.
