"Negate and underdeck a Curse or an Idol. If your lone musician, Priest or Revelation Hero is blocked by more than one Evil Character, Enhancements used by that Hero cannot be negated by an evil card."
Does the second ability mean "at the same time" or "total"? Like would it trigger on add to battles or exchanges, like if the opponent blocks with The Deceiver and then exchanges for a different Evil Character, making 2 total Evil Characters blocking in that battle?
