The extra rule for this mission makes lifesteal units twice as effective. And we throw in some deadly units to shutdown your opponent from going too wide with units. The main strategy of this deck is to combo lifesteal with
Bloodcall Invocation. The bigger the amount of life gain, the better. And you can also combo it with
Wurmstone to deal HUGE damage in a single turn with minimal power.
Piercing Grief is amazing in this fight because of the 12 damage divide (-6 to opponent +6 in life gain) that occurs with only 2 power and an extra 12 when he is drawn with destiny, not to mention
Dark Returning him back to become even more lethal. Remember that the target is chosen at random, so you could get unlucky with targets while your opponent hits all the right shots. Just keep at it!
