Clarification for the "Revised Edition Gameplay" 5/24/2013.The defender and attacker reveal the cards they drew. The defender decides if their hero(es) want(s) to intervene, and intervene(s) if/how they so choose. The attacker then decides if to intervene, and intervenes if/how they so choose.
Then the defender assigns damage/routs from both the unit cards and any possible damage dealt by a hero, and then the attacker assigns damage/routs from both the unit cards and any possible damage dealt by a hero.
Essentially, all the cards are drawn first from any and all sources, then damage/routs are dealt. Heroes always deal damage/routs even if they die in the process.
