FLAME BARRIER. If a Minion attacks each player and Ra's is the 2nd player, he has Flame Barrier and +1 Fire Damage, which would destroy Minion. Does it destroy the minion BEFORE he deals his damage to any hero's after Ra, or is hero damage dealt, then, minion is destroyed? Ra's Barrier was in play before Minion came into play.
You do not have to deal damage in order of players. You can choose Ra to take the damage first, if the Flame Barrier is enough to destroy the target dealing the damage, no other targets will take the damage.
This works for Wraith's Combat Stance and AZ getting hit with Fire damage when he has his transducer out as well
Rather than examples (which will potentially leave out others) let's just say that no damage is simulateous and that 'this trick' works with all instances of retaliation damage or situations where damage triggers an effect that can 'do something', triggers always interrupt the current action.
