"When hero targets deal non-hero character cards 10 or more damage in a single round, destroy this card"
I know that a round is the start of the villain turn all the through the end of the environment turn.
Will Rooftop Combat be destroyed only if one of the heroes deals 10 or more dmage to a non-hero character card? What if 10 or more damage was dealt to multiple non-hero cards by more than 1 hero? I'm assuming the 2nd situation is correct also, but please correct me if I'm wrong.
Yes, these somewhat awkward terms take a bit of getting used to, but it's something that's very important to know in order to comprehend how Sentinels cards work. Many's a time I've failed to notice a distinction between, say, "non-hero targets" (which include environment targets) and "villain targets" (which don't).
Hero Targets have to deal non-hero character cards 10 damage to trigger destruction. The only cards fitting this description are the main villain targets and the Operative, so the Ennead would make it really tough to keep that card out, where as vs. Miss Information you'd have to flip her to get rid of it, and vs. the Dreamer it would be very easy to leave it out the rest of the game.
I wonder if there are any other non-villain, non-hero character cards coming, or if the Operative is the only one.
Phantaskippy had kind of implied that they were "the main character cards", which isn't technically correct - the Ennead as a whole has one card, and each Ennead member has another, all of which are character cards (but the Ennead setup card isn't a target).
Sorry, when I said the Main Villains I meant the ones who fit the name on the card: The Ennead is their name as a whole, so I fit them into that. I can see where the wording would be confusing.
